The Fair Debt Collection Practices Act (FDCPA) permits debt collectors to contact a spouse, a parent of a minor child, a guardian or an executor and to contact other relatives for the purpose of obtaining contact information for one of those four people.
However, the FDCPA limits what collectors can and cannot do in their attempts to collect a debt. Your spouse has the right to tell a collector to stop contacting him or her, with a few caveats: The request must be in writing, and the request won’t relieve your spouse of the debt — that still stands.
