It can take anywhere from a few weeks to a few months to modify a custody agreement in California, depending on the case’s specific circumstances. The process may be relatively quick if both parents agree to the changes. However, the process may take longer if there is a disagreement between the parents or if one parent does not want to change the agreement. In some cases, it may even be necessary to go to court in order to modify the agreement. We can help you navigate the process and ensure that your rights are protected.
