IDEA’s final Part B regulations addressing the due process complaint are found at §§300.507 through 300.509.

(2) The due process complaint must allege a violation that occurred not more than two years before the date the parent or public agency knew or should have known about the alleged action that forms the basis of the due process complaint, or, if the State has an explicit time limitation for filing a due process complaint under this part, in the time allowed by that State law, except that the exceptions to the timeline described in §300.511(f) apply to the timeline in this section.
(b) Information for parents. The public agency must inform the parent of any free or low-cost legal and other relevant services available in the area if—
(1) The parent requests the information; or
(2) The parent or the agency files a due process complaint under this section.
§300.508 Due process complaint.
(a) General. (1) The public agency must have procedures that require either party, or the attorney representing a party, to provide to the other party a due process complaint (which must remain confidential).

(5) A description of the nature of the problem of the child relating to the proposed or refused initiation or change, including facts relating to the problem; and
(6) A proposed resolution of the problem to the extent known and available to the party at the time.
(c) Notice required before a hearing on a due process complaint. A party may not have a hearing on a due process complaint until the party, or the attorney representing the party, files a due process complaint that meets the requirements of paragraph (b) of this section.
(d) Sufficiency of complaint. (1) The due process complaint required by this section must be deemed sufficient unless the party receiving the due process complaint notifies the hearing officer and the other party in writing, within 15 days of receipt of the due process complaint, that the receiving party believes the due process complaint does not meet the requirements in paragraph (b) of this section.
(2) Within five days of receipt of notification under paragraph (d)(1) of this section, the hearing officer must make a determination on the face of the due process complaint of whether the due process complaint meets the requirements of paragraph (b) of this section, and must immediately notify the parties in writing of that determination.
(3) A party may amend its due process complaint only if—
(i) The other party consents in writing to the amendment and is given the opportunity to resolve the due process complaint through a meeting held pursuant to §300.510; or
(ii) The hearing officer grants permission, except that the hearing officer may only grant permission to amend at any time not later than five days before the due process hearing begins.
(4) If a party files an amended due process complaint, the timelines for the resolution meeting in §300.510(a) and the time period to resolve in §300.510(b) begin again with the filing of the amended due process complaint.
(e) LEA response to a due process complaint.

(f) Other party response to a due process complaint. Except as provided in paragraph (e) of this section, the party receiving a due process complaint must, within 10 days of receiving the due process complaint, send to the other party a response that specifically addresses the issues raised in the due process complaint.

However, the SEA or LEA may not require the use of the model forms.
(b) Parents, public agencies, and other parties may use the appropriate model form described in paragraph (a) of this section, or another form or other document, so long as the form or document that is used meets, as appropriate, the content requirements in §300.508(b) for filing a due process complaint, or the requirements in §300.153(b) for filing a State complaint.
