Support orders are based on the facts at the time. Incomes change, jobs end and children's needs grow. When that happens, a child support modification lawyer helps you ask the court to adjust the order.
Timing matters more than most people realize. In most states, a modification only applies from the date you file, not from the date your circumstances changed. Consequently, waiting can cost you money you cannot recover.
This guide explains when child support and spousal support can be modified, how the process works and what it costs. Moreover, it shows how fixed-fee documents can get your request filed quickly.
When child support can be modified
Courts can modify child support when there is a substantial change in circumstances. Common examples include job loss, a significant raise, a change in custody, new medical costs or a child aging into different needs.
Many states also use a numerical test. For instance, a state may allow modification if the new guideline amount differs from the current order by a set percentage. Additionally, some states allow review every few years even without a major change.
Voluntary job changes
Courts look closely at voluntary income drops. If a parent quits a job to reduce support, the court may impute income based on what they could earn. Therefore, be prepared to explain why your income changed.
File promptly — support is rarely retroactive
This is the most important rule. In most states, a modification can only take effect from the date the request is filed or served. Past-due support generally cannot be reduced retroactively.
So if you lose your job today, file as soon as possible. Every month of delay can add debt you still owe. Similarly, if you are the receiving parent and the other parent's income has risen, filing promptly preserves your claim.
Our Child Support Modification service starts at $99. It prepares the motion or petition, the financial affidavit and the guideline calculation. As a result, you can file quickly and correctly.
Calculating the new amount
Child support follows state guidelines. Most use an income-shares model, which combines both parents' incomes. A few use a percentage-of-income model based mainly on the paying parent's income.
The formula also considers health insurance, childcare, other children and parenting time. Consequently, a change in any of these can change the amount. Our child support calculation worksheet shows the likely guideline figure before you file.
Deviations
Courts can depart from the guideline in some situations. Examples include extraordinary medical needs or very high incomes. However, the court must usually explain the deviation in writing.
Modifying spousal support (alimony)
Spousal support follows different rules from child support. Whether it can be modified depends on your state and your agreement. Some agreements make support non-modifiable. Others allow changes for a substantial change in circumstances.
Common triggers include retirement, serious illness, job loss, the recipient's remarriage or cohabitation. For example, many states end alimony automatically on the recipient's remarriage. Furthermore, cohabitation may justify a reduction or termination in some states.
An alimony and spousal support consultation reviews your decree and your state's rules. Consequently, you will know whether a change is possible before you file.
The modification process
First, gather proof of the change. That might be a termination letter, new pay stubs, tax returns or medical bills. Next, prepare the motion and a current financial affidavit. Then file it with the court that issued the order.
After that, serve the other party. Many cases settle once both sides exchange financial information. If not, a hearing follows. The court then issues a new order.
Custody changes and support
If parenting time changes, support should be reviewed too. Read our guide to child custody modification. Similarly, a custody modification consultation can look at both issues together.
