While most people use the terms "full custody" or "equal custody", those are not actual legal terms in Texas. There is a presumption that all separated parents shall be named Joint Managing Conservators which means they share equal rights and duties to their children.
Within that umbrella title, generally one parent will have the exclusive right to determine the child’s primary residence (we refer to this parent as the “Primary Parent”). The child will live primarily with this parent and attend school based upon this parent’s residence. The court will typically limit the area where the child can live which is referred to as a Geographic Restriction. Once a geographic restriction is put into place, they can be very difficult to modify if the future.
The other, non-primary parent, will generally have a Standard Possession Schedule with the child, pay child support, and provide monthly health insurance for the child.
While there are some standard guidelines in place, not all families are the same and there are ways to come to agreements or have the court make orders that either increase the amount of time each parent has with the children or lessen the amount of time based on varying circumstances.
