If your looking to sue your home improvement contractor, New York Lien Law, Section 71-a  might be a good addition to your complaint. In sum it requires your home improvement contractor to deposit certain money received from the home owner, into an escrow account until substantial completion of the work agreed upon in the construction contract. Failure to do so can lead to civil penalties of $2,500. It’s not a huge sum of money in most cases but it’s an easy claim to bring in most cases.

1. Pursuant to New York Lien Law, Section 71-a (4) state in relevant part:
   1. (a) Under a home improvement contract, payments received from an owner by a home improvement contractor prior to the substantial completion of work under the contract shall be deposited within five business days thereafter by the recipient in an escrow account in a bank, trust company, savings bank, or state or federal savings and loan association, located in this state. No depository institution acting on the instructions or otherwise dealing with a home improvement contractor shall be obliged to inquire into the validity or propriety of any deposits to or withdrawals from any escrow account established by the home improvement contractor in compliance with this subdivision or to insure that any withdrawals from such account are applied for any specific purpose or purposes by the home improvement contractor. Such deposit or deposits shall remain the property of such owner except as otherwise provided herein. Unless the home improvement contract specifies the name of the depositary where the funds will be placed, no later than ten business days after the deposit has been made, the recipient shall advise the owner in writing of the name of the depositary where the funds have been placed. The recipient shall not be required to keep in separate depositary accounts the funds of the separate owners from whom payments have been received, provided his books of account shall clearly show the allocation to each owner of the funds deposited in his general or special depositary account or accounts.
   2. (b) In lieu of making the deposit of such payment or payments in an escrow account as provided in paragraph (a) of this subdivision, the recipient may post with the owner a bond or contract of indemnity, issued by a surety company licensed to execute such an instrument in this state, or an irrevocable letter of credit issued by a bank, trust company, savings bank, or state or federal savings and loan institution located in this state, guaranteeing the return of the payments, or the proper application of the payments to the purposes of the contract, which otherwise would be required to be deposited in such escrow account, in which case the recipient shall not be required to deposit such payments in an escrow account. Said bond or contract of indemnity or irrevocable letter of credit shall be delivered to the owner within ten business days after receipt of the payment.
   3. (c) At any time after making the deposit of such payment or payments in the escrow account, the recipient may post with the owner a bond or contract of indemnity issued by a surety company licensed to execute such an instrument in this state, or an irrevocable letter of credit issued by a bank, trust company, savings bank, or state or federal savings and loan institution located in this state, guaranteeing the return or proper application of such payment to the purposes of the contract, in which case the recipient shall not be required to maintain the deposit of such payment in such account.
   4. (d) Such deposit or deposits shall remain the property of the owner or such bond or contract of indemnity or irrevocable letter of credit continued in effect until (i) the proper payment, transfer or application of such deposits by the contractor to the purposes of the home improvement contract under the schedule of payments provided therein; or (ii) the default or breach of the owner excusing the recipient’s performance of the terms of the home improvement contract, but only to the extent of any reasonable liquidated damage amount as defined in section 2-718 of the uniform commercial code and set forth in the contract, and only after seven days prior written notice to the owner; or (iii) substantial performance of the contract.
   5. (e) The recipient shall not withdraw deposits from the escrow account in excess at any time of the total amount shown in the schedule of payments in the home improvement contract. The amount of any such progress payments shall bear a reasonable relationship to the amount of work to be performed, materials purchased, or expenses for which the contractor would be obligated.
   6. (f) If the home improvement contract provides that the home improvement contractor will be paid on a specified hourly or time basis for work that has been performed or charges for materials that have been supplied prior to the time that payment is due, this subdivision shall not apply to such payments for such work or materials.
   7. (g) Failure to place customer deposits in escrow, except as provided herein, shall constitute a violation of this section.
2. The penalty for non-compliance with the aforesaid sections is defined by General Business Law Section 773: “Substantial violations. Every home improvement contractor who fails to deposit funds in an escrow account or provide a bond or contract of indemnity or irrevocable letter of credit in compliance with the requirements of section seventy-one-a of the lien law, or who fails to provide a written contract substantially in compliance with the requirements of this article, shall be subject to a civil penalty not to exceed the greater of two hundred fifty dollars for each violation or five percent of the aggregate contract price specified in the home improvement contract; provided, however, that in no event shall the total penalty exceed twenty-five hundred dollars for each contract.”
