Common mistakes people make filing custody paperwork
Using the wrong or outdated forms
Court forms differ by state, and often by county, and they get updated. Filing an old version, the wrong form, or a form from another county is one of the most common reasons paperwork gets bounced back.
Use the current forms from your own court, and read the instructions that come with them. Many courts publish their forms and a self-help section online.
Vague parenting plans
A parenting plan that is too vague tends to cause problems later and can get tightened up before a judge signs it. Plans that leave holidays "to whoever has the child" or skip exchange details invite future disputes.
Be specific: spell out the regular schedule, who has which holidays and whether they alternate by year, how school breaks are handled, and how and where exchanges happen. Specifics now prevent fights later.
Missing deadlines and skipping proper service
Family cases run on deadlines, and missing one can stall your case or cost you a default. The other side also generally has to be formally served with the paperwork, and doing service incorrectly can invalidate a step you thought was done.
Service rules and deadlines are set by each state and county, so confirm exactly how and when things must be filed and served where your case is. Do not assume a deadline from one state applies in another.
Filing in the wrong court or with incomplete paperwork
Custody matters generally have to be filed in a specific court, often where the child lives, and filing in the wrong place wastes time. Incomplete packets, missing signatures, unsigned declarations, or skipped attachments are another frequent cause of rejection.
Before you file, double-check that you have the right court, every required form, all signatures, and the correct number of copies. A quick review against your court's checklist saves a return trip.
Specifics by state
Family law is state-specific. The general idea is similar everywhere, but the forms, rules, and deadlines vary by state. Here is this topic in the states we cover in detail.
