Would it be ok to just amend the language in the current lease agreement myself, or do I need to get a lawyer to write a new one for me?

Check your laws, see what your options are, and amend the lease to make it easier for the tenant to understand.

I will be amending the lease for the swing set and they will need to get an insurance policy of $2mil plus sign a 'Hold Harmless' agreement, that will be filed. 

Require everyone to sign a lease amendment which will clarify the changes you are making to the lease, or terminate the old lease and enter into a new one with the tenant who stays. 

The tenant has already signed a lease, and has not asked we amend the pet rent.

Going to amend a new lease agreement tonight!

We want our tenant to sign an amendment that the lease is with him and the llc and we are just members of the llc.

Further, in some states and with some escrow/title companies, escrow, title, the realtors or some other third party may require the seller to sign an amendment switching the contract from a cash closing to a financing closing. 

Or should I just make an amendment to the current lease? 

Account Closed In an earlier post I suggested that we should have a law or amendment that requires English to be the official language of the country.
