If one of several co-owners fails to contribute the proportion of the expenditures required for annual labor from the co-owner, the co-owners who have performed the labor or made the improvements may, at the expiration of the annual labor year, give the delinquent co-owner personal notice in writing, or notice by publication in the newspaper published nearest the claim for at least once a week for 90 days and, if at the expiration of 90 days after the service of the notice in writing or 90 days after the completion of the publication the delinquent co-owner fails or refuses to contribute the proportion of the required expenditures, that co-owner's interest in the claim is forfeited to the co-owners who have made the expenditures.
