How child support you pay affects DTI
Child support you're paying is a monthly obligation and is counted in your back-end DTI — just like a car payment or credit card minimum.
Example: You earn $8,000/mo gross and pay $1,200/mo in child support. That $1,200 is subtracted from your borrowing capacity as if it were a $1,200 car payment. On a 43% DTI ceiling, that reduces your available housing + debt from $3,440 to $2,240.
It counts even if it's not reported to any credit bureau. Lenders verify via your divorce or family court decree.
Documentation lenders require
- Divorce or family court decree specifying the support amount and duration
- 3 months of bank statements showing the payment leaving your account (or wage garnishment showing on paystubs)
- State child support agency printout in some states — confirms payment history and no arrears
If you're behind on payments (arrears), most lenders decline until the account is current. Some VA and non-QM lenders will approve with a formal repayment plan in place.
When child support can drop off
If your child support obligation ends within 10 months of the closing date (child turns 18, decree ends), most lenders will exclude the payment from your DTI. You'll need the decree showing the end date.
Otherwise, the payment stays in your DTI for the full loan term.

Frequently asked questions
Is child support treated like a debt on my mortgage application?
Yes. Even though it's not on your credit report, it counts as a monthly debt in your DTI.
What if I pay support in cash?
That's hard to document. Lenders need proof: bank withdrawals, wage garnishment, or a payment log from your state child support agency.
If my child turns 18 in 6 months, does it still count?
Usually no — if the obligation ends within 10 months of closing, most lenders exclude it from DTI.
Do arrears (back child support) affect me?
Yes, significantly. Most lenders decline until arrears are resolved or a formal repayment plan is in place and being paid on.
