Can I protest a will if I have been eliminated by putting forth a lien on the home? This is to retrieve monies that were LOANS to family members.

If you made loans to family members (not the decedent) then your claims for repayment are agains them directly, not the estate.  If you loaned money to the decedent, you can file a written claim against the estate within one year of the date the estate was opened for probate.  Has the will been offered for probate?  Do you think the will is defective in some way?
