We have been in a rental house for a few months now. The landlord signed a lease before he sent it to us. We made some modifications, initialed the modifications, signed the new modified version of the lease and sent it back to the landlord with the deposit. He now says that none of the modifications we added to the lease are valid because he did not resign the new version of the lease with our modifications. We say the new version of the lease and modifications are valid because he accepted the deposit with our version of the signed lease. He has also accepted rent from us for the last couple of months.
Which version of the lease is valid? The modified version actually has both signatures because he signed first before sending the lease to us? His original version only has his signature.
