A qualified domestic relations order (or QDRO, pronounced "qua-dro"), is a judicial order in the United States, entered as part of a property division in a post-nuptial agreement, divorce or legal separation that splits a retirement plan or pension plan by recognizing joint marital ownership interests in the plan, specifically the former spouse's interest in that spouse's share of the asset.

QDROs must first be issued by a State-level domestic relations court, and are then reviewed by plan administrators for compliance with the terms of the plan and with ERISA or other applicable law. The QDRO may be a separate document or it may be part of a divorce decree, and is valid as long as it meets the standards for a qualified domestic relations order under ERISA and meets the standards of the plan to which it applies. Courts have jurisdiction to declare a QDRO "qualified" as comporting with federal law, but pension plan administrators must determine whether a QDRO meets the requirements of a specific pension plan.
