If my husband of 22 years of marriage is lying at the Office of Admissions and Records by saying that I gave him my part of the property, by forging my signature on a legal document, and while being under a restraining order he adds his sister in the title of the Dean, what legal actions can I take towards him?

What country is this? The wording does not sound like America. This is an international site.

But the action seems criminal, so it sounds like you file criminal charges.
Then sue civil court to restore the deed.

Any question on law needs to include your general locale as laws vary by area.

Generally, if you can prove forgery, you will need to file criminal charges against your husband.

You will need to challenge your signature and there may be a court case where he will have to prove you signed.

You may need a lawyer to help protect yourself, and your property against this rascal of a husband. Are you also going through a separation, or divorce? Sounds like he is thinking of one even if you are NOT.

Having your legal rights, and options explained to you ASAP, by a professional is EXACTLY what you need to settle this, AND protect your own interests, from what you have written.
