What piece of legislative allowed Great Britain to borrow military equipment?

The piece of legislation that allowed Great Britain to borrow military equipment from the United States during World War II is known as the Lend-Lease Act.

It facilitated the supply of war materials and equipment, thereby strengthening the Allies against Axis powers.
