We have customer who has owed us 20k since the end of July. He did not pay for the services as per the contract, stating he needed to wait until the sale went through (after the fact). At this point, we feel we need to lien the property to ensure payment. That said, our contract accrues monthly interest. I was curious if the interest could be applied to the lien after the lien itself has been filed. (Ex. Lien filed in December, we are in June of the following year, thus 6 more months of interest would be accumulated.) Would that amount be accounted for?
