These skin cells are known as buccal cells, and they rub off easily onto cotton swabs and remain in place for analysis by our laboratory. Other specimen samples, such as hair follicles, fingernails, and garments that might contain someone's DNA, can also be tested. An Alternative Specimen DNA Test is done by registering online and shipping the specimens to us.

Establishing Paternity in Catonsville, MD

For unmarried Catonsville parents, establishing paternity in the state of Maryland is important for a multitude of reasons. For one, it legally establishes a child's connection to his or her biological father, allowing them to receive benefits such as inheritance, health, and social security. Furthermore, if either parent requires monthly child support services from the other parent, proof of a legal paternity establishment will be required.

Under Maryland law, a Catonsville parent can legally establish paternity by one of two ways. If both parents are willing to establish paternity and agree on their child's paternity, the two should complete an Affidavit of Parentage. This document is completed by both parents at the hospital and becomes a legally binding connection between child and father once completed. If one parent encounters difficulties having the other establish paternity, they will need to file a paternity petition with Baltimore County Family Court. The courts will then use DNA testing to accurately determine a child's paternity and rightfully establish paternity.

Withdrawing a Paternity Establishment in Catonsville, MD

Although a Catonsville couple may quickly establish legal paternity following their child's birth, they may soon discover that the presumed father is not the biological father. Unfortunately, since a paternity establishment is a legal standing, it can be difficult to rescind the affidavit in court. However, the state of Maryland does provide a 60-day window following the signing of the affidavit to submit a Rescission Form and have it nullified.

If this 60-day mark passes, the couple will need to request to have the establishment rescinded in Baltimore County Family Court. The court will require proof of fraud, duress, or material mistake at this time. The court may also request DNA paternity testing to support the invalid paternity claim.

Experts in Catonsville, MD Say…

When two Catonsville parents can't settle on a co-parenting plan that works in the best interest of the child, they should seek the assistance of Baltimore County Family Court. A judge will assess the child's current situation to create a plan that works in the best interest of the child and ensures all needs are met. According to Catonsville Family Law Attorney Kevin Beard, the state of Maryland uses several factors when deciding what is best for the child. This includes the child's preference, parents' living situations, reputation, and prior proof of voluntary abandonment or surrender of custody.
