I have a question regarding constitutional liens in Texas. When a vendor issues a Claim of Lien to the owner, what is the time frame for enforcement? Statutory liens have a one- or two-year deadline to enforce, but it's unclear to me if this applies to constitutional liens. Does the "catch-all" of four years apply here once the Claim is issued or does the vendor have to meet the one/two-year deadline above? It may be helpful to note that no written contract exists covering the relationship.
