The Family Violence Prevention and Services Improvement Act of 2026 substantially expands federal support for domestic violence prevention and services by updating definitions to include technological and economic abuse, establishing new grant programs for underserved populations including Alaska Native tribes and Native Hawaiians, and creating specialized funding for services targeting LGBTQ+ victims, people with disabilities, and American Indian and Alaska Native communities. The bill strengthens state grants by expanding eligible populations and giving the Secretary discretion to waive matching fund requirements for states in hardship, while simultaneously authorizing new national resource centers, technical assistance programs, and a 24-hour hotline specifically serving Native Americans. Additionally, the legislation funds evidence-based prevention initiatives at state, tribal, and local levels, extends grant periods for programs serving children exposed to domestic violence, and establishes capacity-building grants for culturally specific shelter and support services in marginalized communities. The bill streamlines outdated requirements and removes barriers to tribal access to federal funding, ensuring that vulnerable populations receive better coordinated, culturally appropriate domestic violence prevention and victim services across the country.
