Generally speaking, no matter your relationship status, you can adopt. The only age requirement is that the party or parties adopting must be 21 years of age or older. A single individual may choose to adopt but if a couple adopts together, both must petition for the adoption.
Parents who are interested in adopting must first be approved by a state-licensed home study provider. Through a series of interviews, home inspections, and background checks, the person or family will be evaluated to ensure they’re in a good place to proceed with the adoption process.
Any kind of couple can adopt if they are approved. The process may vary slightly, based on required paperwork for your relationship and state in which you reside.
