## Definition of Lease
A lease is an agreement whereby the lessor (legal owner) conveys to the lessee the right to use an asset for a period of time in return for a payment or series of payments called lease rentals.
### Key Parties
| Party | Role |
|---|---|
| Lessor | Legal owner who gives the right to use the asset |
| Lessee | Party who receives the right to use the asset |
### Key Terms at a Glance
- Lease Term: The agreed duration of the lease
- Lease Rentals / Lease Payments / Minimum Lease Payments (MLP): The consideration paid by lessee to lessor
### Why This Matters
AS 19 governs how leases are recorded in the books of both the lessor and lessee. The entire treatment — journal entries, balance sheet presentation, income/expense recognition — depends on correctly identifying the parties and the type of lease.
