When Modifications Are Necessary

To modify an existing custody or support order, you must show that your situation has changed significantly since the original court order was issued. Some common reasons include:


  • Child Custody Changes: Shifts in work schedules, remarriage, or your child’s changing needs may require updates to custody arrangements.
  • Parenting Time Adjustments: If your child’s schedule, health, or educational needs have changed, you may seek to revise visitation or parenting time.
  • Child Support Modifications: If you or the other parent has lost a job or faced a substantial change in income, adjusting child support can help maintain a fair balance.
  • Relocation Issues: A move to a new city or state often requires a review of existing custody and support orders to ensure they still serve your child’s best interests.


How the Modification Process Works

  • Petition to Modify the Parent-Child Relationship
    To begin, you file a document explaining the major changes that justify modifying the original order. If both parents agree to the new terms, we can often move the process along quickly.
  • Resolving Disputes
    If you and the other parent do not agree, our attorney will represent you in court. We gather evidence, prepare testimony, and advocate for the arrangement that fits your child’s best interests.
  • Finalizing the New Order
    Once the judge approves the modification, you will have a new legal order reflecting the updated custody or support terms. Both parents must follow these terms until changed again by the court.

Child Custody Articles

Few situations are as frustrating as someone else being legally recognized as the father of your child. Yet, in Texas, this can happen due to “presumed fatherhood.” Thankfully, this legal presumption can be challenged. This article breaks down everything you need to know about presumed fatherhood in Texas, including: What presumed fatherhood means in Texas law and the rights it grants. How to defend or challenge presumed fatherhood. How presumed fatherhood affects child support, custody, and conservatorship. What Is Presumed Fatherhood Under Texas Law? In Texas, presumed fatherhood occurs when a married woman has a child—meaning her husband is automatically considered the father of that child. This presumption simplifies legal matters in most cases, but it can also create complications, especially in divorce cases or situations where paternity is in question. If both parents agree that the husband is the father, paternity can be acknowledged on the child’s birth certificate, and he becomes both the presumed and acknowledged father. However, things can get more complicated when the biological father is someone other than the husband. For example, if the mother is pregnant during a divorce, it is crucial to address paternity. If the husband is not the biological father, steps must be taken to ensure he is not incorrectly recognized as the father, which could lead to legal and emotional complications later on. These situations can be uncomfortable to discuss, but honesty is essential to prevent future issues. The more openly you discuss the details with your attorney , the better they can help navigate the legal process. What Legal Rights Does A Presumed Father Have In Arlington, Texas? In Texas, a presumed father is considered the legal father of a child, with the same rights and responsibilities as any parent. If a child is born during a marriage, the law automatically assumes the husband is the father. This means he can: Enroll the child in school Take the child to daycare or doctor appointments Make medical decisions for the child Handle other day-to-day parental duties However, there are situations where the presumed father may not actually be the biological father. In those cases, someone might want to challenge the presumed father’s rights. This can be done by either signing a denial of paternity or going to court to establish who the real biological father is. On the flip side, if the presumed father wants to remain the legal father (even if he’s not biologically related), and the mother agrees, they can go through a process where the presumed father acknowledges the child, similar to an adoption. Here’s how this might look: Child Born Before Marriage If a child is born before the couple marries, but the husband is listed as the father on the birth certificate, he becomes the legal (or acknowledged) father, even if the child was born before they were married. Child Born During Marriage If a child is born while the couple is married, the law assumes the husband is the father, making him the presumed father. Once his name is on the birth certificate, he is the acknowledged father. Now, imagine the couple is going through a divorce, and the mother claims the husband is not the biological father of the first child. While there are limits to how long after birth this can be challenged, situations like this do happen. In such cases, being the presumed father becomes important. Often, the presumed father either remains the legal father, or there is a legal process to determine the biological father. During a divorce or any legal proceedings, it is crucial to clarify who the father is, especially if there’s any doubt. Even if the child was born during the marriage, leaving this issue unresolved can lead to confusion and legal problems later on. Making sure everything is clear protects everyone involved, especially the child. Can A Presumed Father Fight For His Rights Even If He Is Not The Biological Father? In Texas, a presumed father has certain legal protections, even if he is not the biological father. These protections are designed to prevent a presumed father from losing his rights, especially if he has been actively involved in the child’s life. One key protection is the limit on when presumed fatherhood can be challenged. After the child’s fourth birthday, it becomes much harder to challenge a presumed father’s rights, even if the mother denies paternity. For example, if a man has raised a child for 16 years as the presumed father, the law recognizes him as the legal father, regardless of biology. This means he can fight to keep his rights to custody and visitation. At this stage, the mother cannot challenge his paternity, and the court will likely uphold his parental role. One reason the law protects presumed fathers after the child’s fourth birthday is to prevent the emotional damage that can occur when a child suddenly loses a parent figure. If a man has raised a child for years, denying his paternity is not only harmful to him but especially traumatic for the child. Courts recognize that children benefit from stability, and removing a presumed father after years of bonding can cause lasting harm. Because of this, if you are considering challenging a presumed father’s rights, it’s important to act quickly—before the child turns four—to avoid emotional damage and ensure the legal process is handled as smoothly as possible. What Happens If A Paternity Challenge Occurs Before A Child Turns Four? If a challenge to paternity occurs before the child’s fourth birthday, the situation changes. During this time, if the mother denies paternity or another man claims to be the biological father, a DNA test can be requested. If the test shows that the presumed father is not the biological father, his legal rights could be revoked. In these cases, the presumed father may lose his ability to fight for custody or visitation, no matter how involved he has been in the child’s life. This can be a painful and difficult process, particularly for a presumed father who has been fulfilling the parental role. Unfortunately, the law in these cases prioritizes biological parenthood. How Does Presumed Fatherhood Impact Child Custody Or Child Support? In Texas, a presumed father has the same rights and responsibilities regarding child custody and child support as any other father, whether biological or not. The fact that a father is presumed rather than confirmed through DNA does not change his ability to seek custody or be ordered to pay child support. However, the situation can change if paternity is challenged. If the mother denies that the presumed father is the biological father, or if another man claims to be the biological father, this could affect the presumed father’s rights—especially if the challenge happens before the child’s fourth birthday. If no one challenges the presumed fatherhood, he retains all the legal rights of any father, including the ability to seek custody, visitation, and even primary conservatorship (custody). He could also receive child support from the other parent, depending on the circumstances. Is There A Benefit To Having Presumed Fatherhood Legally Acknowledged? Yes, having your presumed fatherhood formally acknowledged can provide long-term protection. You can solidify your status by being listed on the child’s birth certificate, signing an acknowledgment of paternity, or obtaining a court order. While it is still possible for someone to challenge your paternity later, a formal acknowledgment makes it much harder to contest. Once your fatherhood is formally recognized—especially if the mother has signed off on it—it becomes more difficult for her to challenge it in the future. By taking these steps, you are not only protecting your rights but also ensuring that your role as the child’s legal parent is secure. How Is Presumed Fatherhood Legally Challenged In Arlington, Texas? In Texas, there are two main ways to challenge presumed fatherhood: 1. Signing A Denial Of Paternity If all parties agree, the presumed father can sign a denial of paternity. Afterward, the biological father and the mother would both sign an acknowledgment of paternity, establishing the biological father’s legal rights. 2. Filing A Suit To Establish Paternity If the presumed father believes he is the biological father, or if someone else (like the mother or another alleged father) challenges his status, a paternity suit may be necessary. This process typically involves a DNA test to determine whether the presumed father or another man is the biological father. Once the results are in, the legal paternity can be settled, and related issues like child support and custody can be addressed. Importantly, if you want to challenge presumed fatherhood, this process must be initiated before the child turns four. After that, your options are limited. What Happens If I Miss The Deadline To Challenge Presumed Fatherhood? If you miss the deadline to challenge presumed fatherhood (before the child’s fourth birthday), the presumed father is legally recognized as the father. This means he will have all the rights and responsibilities of a parent, including the ability to seek custody and visitation rights. If he and the mother separate later, the presumed father will continue to have the same parental duties as any other legal father. Can A DNA Paternity Test Change Anything After Age Four? After a child turns four, getting a court to allow a DNA paternity test becomes much harder. Texas law includes the four-year limit for a reason, and a judge can refuse DNA testing if the presumed father has been acting as the child’s father for years. Even if a biological father steps forward later, the court may argue that the presumed father has fulfilled the parental role, regardless of biological connection. In these cases, the presumed father can continue to have rights to custody, visitation, and decision-making for the child, just as if he were the biological father. This is why it is important to act within the legal timeframe if there’s any doubt about paternity. Still Have Questions? Ready To Get Started?

Few endeavors are as impactful as parenthood, but what does it mean in the eyes of Texas law? Who gets to claim the privileges and responsibilities of being a legal parent? In this article, we explore the legal framework surrounding parent-child relationships in Texas, specifically for Arlington residents, covering topics such as: How the parent-child relationship is defined and established (even without DNA testing). How legal procedures differ for married and unmarried parents in Texas. The significance of establishing a parent-child relationship, and how grandparents can do it. How Is A Parent-Child Relationship Legally Defined In Texas? In Texas, a parent-child relationship can be established in several ways. According to state law, this relationship can be recognized as: A mother who gives birth to the child A parent who adopts the child Additionally, Texas law provides specific processes that outline how the parent-child relationship can be established beyond biological birth. The legal system acknowledges that families can take various forms and strives to ensure that once a parent-child relationship is established, it is fully respected under the law. Can A Parent-Child Relationship Be Established Without DNA Testing? Yes, DNA testing is typically required in cases where paternity is disputed—such as when the mother denies the father’s paternity or the father denies his relationship with the child. These situations are the most common reasons DNA testing is used before legal proceedings can move forward. However, outside of these cases, DNA testing is not necessary. Texas law allows for the establishment of a parent-child relationship through an acknowledgment of paternity (AOP), which is a formal legal document. Additionally, if both parents are listed on the child’s birth certificate, this can also serve as proof of the parent-child relationship. In cases where further legal action is needed, an adjudication, or court order, can be issued to formally establish the relationship. These various legal options ensure that parenthood can be recognized without requiring genetic testing in all cases. What Documents Are Needed To Establish A Parent-Child Relationship? The most common documents needed include: The child’s birth certificate Acknowledgment of paternity A court order, such as an adjudication These legal documents serve as proof of the parent-child relationship and are essential for matters related to custody, support, and inheritance. How Does The Legal Process Differ For Married And Unmarried Parents In Arlington, Texas? Both married and unmarried parents in Texas can establish a legal parent-child relationship, but the process is a bit different for each. For married couples, the law automatically assumes that the husband is the father of any child born during the marriage. While this is helpful in many cases, it can create challenges if the husband is not the biological father. For instance, if a married woman has a child with someone other than her husband, all three people—the mother, her husband, and the biological father—must follow certain steps to legally establish who the child’s father is. This includes: Filing a legal case to establish paternity Getting a court order (called an adjudication) to confirm the biological father Having the husband sign a denial of paternity Having both the mother and the biological father sign an acknowledgment of paternity This situation is more common than you might think, especially if the parents are in the middle of a divorce. Even if the child isn’t the husband’s, the paternity must still be addressed during the divorce proceedings. If everyone is on good terms, this process can be smoother, but it still requires legal steps to ensure everything is settled correctly. What Is The Legal Significance Of Establishing A Parent-Child Relationship? The main reason for legally establishing a parent-child relationship is that it gives parents the ability to enforce their rights and take on the responsibilities of raising their child. While many people see this as just a step toward securing child support, it is about much more than that. Without a legal order in place, one parent—often the one who has primary possession of the child—may make decisions that affect the other parent’s rights. While most people picture the mother as the primary caregiver, that’s not always the case. In fact, many fathers have the misconception that they have fewer rights than mothers, but this is not necessarily true. If a father wants to ensure his parental rights are fully protected, it is essential to establish a legal parent-child relationship. This step allows fathers to make sure their role in their child’s life is clear and recognized. For separated parents, getting a legal order that outlines custody, visitation, and child support is crucial. The more detailed the agreement, the better—because if problems arise, such as the other parent not respecting your visitation rights, you’ll have the legal grounds to enforce the order and protect your time with your child. Relying on informal agreements or verbal promises often leads to issues down the line. By securing a legal order, both parents’ rights are clearly defined, and you have the ability to hold the other parent accountable if things change. How Can A Grandparent Establish A Parental Relationship Over A Grandchild? If you are a grandparent raising your grandchild, you may be able to obtain the legal rights and responsibilities of a parent, but it is important to understand that the Texas Family Code has a “parent fit” presumption, and you will need to overcome this if you want to establish legal parental rights. The law assumes that parents are capable of raising their children, so for a grandparent to step in and gain parental rights, they must prove that the biological parent is unfit. This can be challenging—simply claiming that the parent is unstable, irresponsible, or financially struggling is not enough. You’ll need concrete evidence to convince a court that the parent cannot provide a safe, stable environment for the child. For example, if your son or daughter dropped off their child at your home temporarily, and it has only been a day or two, you can’t file for parental rights just because you are concerned. However, if there has been an extended period without communication, and you are worried about the child’s well-being, you might want to take legal action to protect the child and ensure you have the authority to make decisions for them. In such cases, you will need to locate the parent, notify them, and serve them legal papers—but this is just the first step in what can be a complicated process. Although it may feel frustrating to go through so much, it is necessary unless it is an emergency where Child Protective Services (CPS) is already involved. If CPS is involved and the child has been placed with you in an emergency situation, the process may move faster. However, if CPS is not involved, you’ll need to act as the child’s primary caregiver for at least six months before you can file for parental rights. After six months, you can file to request parental rights, establish a visitation schedule, and seek support from the biological parents. Keep in mind that during those six months, you’ll need to be fulfilling the day-to-day responsibilities of being a parent. The court will want to see that you’ve already been acting in the child’s best interests before it will consider granting you legal recognition of that role. There are situations where you may be able to file sooner. For example, if the parent has been absent for a few months but returns in a state of instability—such as being intoxicated or belligerent—or tries to disrupt the child’s life by pulling them out of school, you may have grounds to file earlier. In any case, you will need to show that continuing to allow the biological parent full rights would negatively impact the child and that you can provide a better, safer environment. Ultimately, the court’s goal is to ensure that the child’s best interests are protected, providing them with a stable, non-violent environment where they can thrive. What Are Some Consequences Of Failing To Establish A Parent-Child Relationship? Failing to establish a legal parent-child relationship can have serious consequences. Without this legal recognition, you won’t have access to important rights and privileges that are essential for both you and the child. No Access To Child Support One of the most immediate consequences is that you won’t be able to receive child support. While raising a child is rewarding, it can also be financially challenging. Without financial support, covering the costs of raising a child—such as healthcare, education, and everyday needs—can become overwhelming. Establishing the parent-child relationship ensures that the child receives the financial resources they need. Limited Decision-Making Power Another major consequence is losing the ability to make critical decisions for the child. For instance, during the COVID-19 pandemic, many parents and caregivers faced disputes over whether or not to vaccinate their children. If you haven’t legally established the parent-child relationship, you won’t have a say in these important decisions. However, by legally establishing the relationship, you can determine which parent has the right to make major decisions or whether both should share those responsibilities. In some cases, you could even contest a decision in court. Loss Of Visitation & Custody Rights Establishing the parent-child relationship is also crucial for securing your right to spend time with the child. If you do not have legal recognition, the primary parent could limit or control when and how you see the child. A court order that defines the parent-child relationship will protect your rights and establish clear terms regarding custody and visitation. These orders can cover details as specific as when and where child exchanges take place, ensuring both parties follow agreed-upon arrangements. Inability To Prevent Unilateral Changes Without a court order protecting your parent-child relationship, the other parent could make significant changes—such as moving to another state—without consulting you. When a legal relationship is established, neither parent can make such changes without the other’s agreement or a new court order. Still Have Questions? Ready To Get Started?
