Adele reportedly had her new husband, Rich Paul, sign a prenuptial agreement before their secret wedding to protect her $220 million fortune. Adele's friends allegedly urged her to put the prenup in place to safeguard her assets. The singer's fortune includes her salary from her Las Vegas residency, album sales, and digital sales. Her Las Vegas shows are expected to generate $2 million per show in gross revenue, making her the highest-earning artist in Vegas history.

Adele also owns several properties, including an $11 million estate in West Sussex, a $10.5 million property in Beverly Hills, a $9.5 million home in Los Angeles, and two townhouses in London valued at $14 million. In December 2021, she purchased Sylvester Stallone's mansion in Beverly Park for $58 million and embarked on a renovation project. Adele has previously referred to herself as a married woman, and at one of her Las Vegas shows, she disclosed her marital status during a conversation with an audience member.

She joked about being proposed to and stated that she is with Rich and is his wife.
