32 CFR 536.29 - Revision of filed claims.
(a)General. A revision or change of a previously filed claim may constitute an amendment or a new claim. Upon receipt, the CJA must determine whether a new claim has been filed. If so, the claim must be logged with a new number and acknowledged in accordance with § 536.27.
(b)New claim. A new claim is filed whenever the writing alleges a new theory of liability, a new tortfeasor, a new party claimant, a different date or location for the claims incident, or other basic element that constitutes an allegation of a different tort not originally alleged. If the allegation is made verbally or by e-mail, the claimant will be informed in writing that a new SF 95 must be filed. A new claim must be filed not later than two years from the accrual date under the FTCA. Filing a new claim creates an additional six month period during which suit may not be filed.
(c)Amendment. An increase or decrease in the amount claimed constitutes an amendment, not a new claim. Similarly, the addition of required information not on the original claim constitutes an amendment. Examples are date of birth, marital status, military status, names of witnesses, claimant's address, description, or location of property or insurance information. An amendment may be filed before or after the two year SOL has run unless final action has been taken. A new number will not be assigned to an amended claim; however, a change in the amount will be annotated in the database.
