It is helpful if you can provide the non-custodial parent’s address, social security number, date of birth, employer, bank account numbers, property holdings and investments. Look for this information in old insurance policies, credit card or other applications, state and federal tax returns, hospital records, police records, birth certificates and social network websites.
You may be able to get information from the non-custodial parent’s business associates, friends, or relatives. Also, please provide copies of any existing court orders and records of payments.
If you can provide the non-custodial parent’s date of birth, father’s name, and mother’s maiden name, the child support agency may be able to obtain information from the Social Security Administration, the Internal Revenue Service, the Veterans’ Administration, the Department of Defense, the Armed Forces, and/or the Selective Service Administration.
If you can provide the non-custodial parent’s social security number and / or date of birth, the child support agency can obtain information from all state and federal files. Be aware, however, that finding a non-custodial parent through these sources may take several months.
