The lawyer for the woman who accused Lindsay Lohan of battering her says he's been told ... if his client submits a declaration to the D.A. stating she's not pursuing the case, the investigation will be dropped ... And she just submitted the declaration.
Dawn Holland, who has been fired from Betty Ford, says in the declaration -- obtained by TMZ -- "I do not desire Ms. Lohan prosecuted for the events of December 12, 2010," adding, "I will not answer any questions to any policing or prosecutorial agencies regarding the events of December 12, 2010."
Holland's lawyer, Keith Davidson, tells TMZ, the D.A.'s Office informed him today ... if such a declaration were filed, the case against Lindsay would be rejected.
The declaration follows an angry letter Davidson sent to the D.A., scolding prosecutors for trying to interview his client after she repeatedly told them she wanted nothing to do with the case.
The D.A.'s Office had no comment and says the matter is still under review.
