Warranty or Quit Claim deed

I purchased this propery in 1982 after my husband died. The property is in my name alone and no mortgage or leins on the property. I have 2 adult children. I remarried in 1994 and my present husband wants his name on the deed, of which I said NO that this was purchased prior to our marriage. I want to protect the property for my 2 children after I die. We have other property which was purchased after 1994, this property is only in mine and my husbands name. I have no will or any other directives at this time (I'm 74) Is a quit claim or warranty deed the best way to go? How can I be sure that after I die that my kids will get my part of the property purchased after 1994, he will not consent to a will or putting their names on the property which is also free from debt. Thanks for your help.
