If my name is on the deed can a sibling contest this after my father dies?

A deed is much more difficult to contest than a gift in a Will or a Trust.   It also depends how title is held to the real property - if someone is named as a co-tenant (co-owner) then there is not a right of survivorship.  If someone is named as a joint tenant (also a co-owner), there is a right of survivorship.  Or if someone has been named as the sole owner on a deed - then title is clearly in that person's name.  There is not enough information about how title is held to be able to give better feedback.
