In this particular situation, We have an emailed and accepted agreement (no signed contract). I have performed over 90% of the agreed work and gave them an invoice for travel costs up to this point. I told them I would charge a daily trip fee for every day worked in our very first correspondence and have clearly accepted by hiring me. Instead they told me to "get out" without paying or offering payment. They have since retained an attorney who has sent me a letter affirming they received my invoices for the agreed upon work, but also saying they owe me nothing and to not contact his clients directly, but instead send all future correspondence to him. In Texas I know I cannot file and perfect a statutory lien, but there is a constitutional lien option here I believe I can use. The letter goes on to say the property is a "homestead" which is why I cannot file a statutory lien having no prior notification of work being performed to the county. This is news to me since I do not have complete information on their assets and do not know if they own other properties or which one they consider their homestead. Seems to me I should be able to file for a Constitutional Lien since I can prove an agreement was offered and accepted and I have produced over 300 hours of work with only materials being paid to date. The agreement clearly stipulates the agreed upon price and payments are to be made at milestones. The letter I received is so inflammatory and over the top I figure they are simply trying to dissuade me from exercising my legal rights to collect payment since their case would be very hard to win if litigated. Do you agree? I know I will need to send notice of any Lien to their representative (in this case their attorney) since I cannot send it directly to them now, but what else should I be doing? I can't imagine they plan to litigate this for how little they owe me (you should see the pictures I have, they were getting an exceptional deal on exquisitely detailed work). What can I expect to see if I do file a lien and is there anything I should avoid doing?
