If this deadline is missed, the claimant will lose their lien rights. Also, if the deadline ends up falling on a weekend or federal holiday, the deadline will be extended to the next business day. Once filed, a copy should be sent to the owner within 14 days of filing the claim. failure to send this notice doesn't invalidate the lien, but it will bar the claimant from being able to recover attorney fees and costs if the lien is eventually foreclosed. Keep in mind, that Washington does have preliminary notice requirements. The general rule is everyone is required to send notice to secure their rights, but there are a few exceptions to this requirement.
