Yes. A lease is a contract and to make it enforceable by either party both must sign.
For the lease to be valid all fee owners must sign it.
The legal agreement necessary for a rent by owner arrangement is known as a "Tenancy Agreement". This agreement defines the responsibilities of both landlord and tenant.
No. Both owners must sign the agreement to make it legal and enforceable for both tenant and landlord.
Unless the unwilling signatory can show that he was coerced (forced) into signing the agreement YES.
If a damage deposit is/was a term of your Residential Tenancy Agreement, then yes. If there was no provision for a damage deposit when you signed the agreement, then the terms cannot be changed until the agreement expires, or both parties agree to the change in writing.
No, as both signatures are needed for a passport.
Any transaction can be initiated by either party, but the signatures of both will be required on the deed-in-lieu agreement and property transfer documents.
If you signed it, you are bound by the terms. Not giving you a copy does not relieve you of your duties.
Generally, and in Florida, a tenancy by the entirety is a special joint tenancy reserved for legally married people. They own the property with the unseverable common law right of survivorship. If one dies, the other automatically owns the property. With a general joint tenancy with the right of survivorship the tenancy can be broken by one of the parties and it will transform into a tenancy in common. The right of survivorship within a tenancy by the entirety cannot be severed by one of the parties. One may not sue the other to Partition the property. A creditor of one may not claim the property or the proceeds of sale. In Florida, the signature of both spouses is needed to sell the property and one cannot sell their interest alone. Both are required to sign a mortgage or any other type of contract.
In the first application for a divorce only one signature will do but finally on the final form both the wife and the husband should sign , then only will it be of value .
I don't think there are any laws which state that a lease must be neatly typed. They can be handwritten as long as both side know and agree to the terms of the lease.
Technically yes they can but if both executors are named on the Grant of Probate then both signatures would be needed to cash in any assets.
If the title has more than one name on it then yes. Or if you mean buyer and seller signature that is also yes.
