I refused to settle for this situation, so I called one of the lawyers listed on the British Embassy´s website. This one;
10. Mrs. Maria Boneva
Specialist in immigration, commercial, contract, tax, family and estate law. English spoken.
Address: 3, Parchevich St., Varna
Tel: (052) 605 006; (087) 665 884
They referred me to an accountant (with the same last name) , who was very helpful, spoke perfect english and agreed to do the tax return in this short amount of time! For 300 leva, thats approx. 150 euro, NOT 350!. It was all done in time, even though it took a while for them to reach my lawyer. They also had to get papers from another city from the agency who sold me my properties, that I had been under the impression my lawyer had already fetched. All in all they did a great job, explained the procedure, coped with the difficult lawyer, and answered my emails immediately.
