What must be in the land lease agreement?

If the lease agreement was only verbal (owners avoided signing...?

...paper version, motivating by trust), then were they supposed to enter their housing, which they rented according to a verbal agreement, took payment (partially and in advance), without the presence of the lodger? I was told that yes, because they are the owners "whenever we want - then we will come, we have the right to enter without you." Is it so by law?

Is it necessary to notarize a lease agreement for non-residential property?

Is it possible to terminate the land lease agreement unilaterally...?

... with compensation to the lessee for lost funds (the leased land is seized, which prevents the lessee from using it, but the rent is paid, and the lessor does not want to terminate the lease agreement)

Will the lease agreement for an apartment in the occupied territory be valid?
