Got an eviction notice? Most tenants never respond and lose automatically. The ones who respond do far better. TenantShield walks you through it in plain language. - See your response deadline first, so you do not miss it. - Answer a few simple questions to find the defenses that may apply to you. - Organize your evidence by the defense it supports. - Prepare an Answer document you can review, sign, and file yourself. TenantShield is a self-help tool - not a law firm, and not legal advice. It helps you understand your situation and prepare your own documents, and it points you to free legal help. You review and file everything yourself, and you should talk to a lawyer or legal aid. Deadlines shown are estimates; always confirm with the court. Your case stays on your phone. No account, no tracking, nothing uploaded. Currently supports Michigan, California, New York, and Texas.
