I think you'll find most, if not all title insurers, will require the DIL to be dated and executed subsequent to default in order to insure. In addition, the Grantor will probably be required to sign the same seller's affidavit that are needed for a non DIL closing. Here's a short treatise by a title insurer:
A deed in lieu of foreclosure is a deed given by the owner of mortgaged property to the holder of the mortgage or its designee where the mortgage is in default and foreclosure is a possibility. A deed is given and accepted as an alternative to ("in lieu of") foreclosure. Unlike a foreclosure, a deed in lieu of foreclosure does not extinguish any of the liens and encumbrances affecting the property.
Most courts recognize the execution of a deed in lieu of foreclosure in a transaction subsequent to the original mortgage transaction as a legitimate alternative to foreclosure proceedings. However, deeds in lieu of foreclosure can be subject to judicial attack by their grantors and their grantors' creditors.
Grounds for attacks on deeds in lieu of foreclosure include the following:
• That the deed was an equitable mortgage - that the parties intended the deed to be given as security for a debt and that the deed was not an absolute conveyance.
• That the deed is either a preferential or fraudulent transaction within the purview of the provisions of the federal Bankruptcy Act or any other related state law.
• That the deed is a device to clog a mortgagor's right of redemption.
• Unfairness of the consideration.
• Coercion, fraud, oppression, duress, and undue influence.
• That the deed is not subsequent to the execution of the mortgage but contemporaneous with it.
• That the grantor/mortgagor was insolvent at the time of the execution of the deed.
An estoppel affidavit (executed and acknowledged by the grantor/mortgagor, attesting to the fairness of the transaction, the consideration exchanged, the value of the property, and other factors showing an intention to make a genuine transfer) or a recital (inserted directly in the deed) are supporting documents used to forestall challenges to these transactions.
State law and local title standards must be consulted in regard to the consideration and treatment of deeds in lieu of foreclosure.
