CFIUS does not issue advisory opinions as to whether a transaction is a covered real estate transaction or might raise national security concerns.  CFIUS will not accept or review draft declarations.


The regulations at 31 C.F.R. § 802.402 specify the required contents of a real estate declaration.  Starting on June 1, 2020, real estate declarations must be submitted through Case Management System portalSee the Case Management System page for more information.


Upon receipt of a declaration submitted pursuant to 31 C.F.R. § 802.401, the Staff Chairperson will promptly inspect the declaration for completeness.  Upon determining that the declaration meets all requirement sunder 31 C.F.R. § 802.402 and, therefore, is complete, the Staff Chairperson will accept the declaration and circulate the declaration to all CFIUS agencies.  Upon accepting a declaration, the Staff Chairperson will promptly notify the parties in writing of the date that the assessment period started.  This assessment period ends no later than the 30th day after it has commenced, or if the 30th day is not a business day, no later than the next business day after the 30th day.  The Staff Chairperson or another Treasury Department official will advise the parties in writing if CFIUS requires further information or action by the parties.

Throughout the declaration assessment period, parties must respond to requests for information within two business days of the request or within a longer time frame if the parties so request in writing and the Staff Chairperson grants that request in writing.


Each party to a transaction submitting a declaration must provide, via the Case Management System portal, a certification of the information contained in the declaration consistent with 31 C.F.R. § 802.202.  The certification must be signed by the chief executive officer or other duly authorized designee of each party to a transaction filing a declaration.

If the Committee notifies the parties to a transaction that have submitted a declaration pursuant to 31 C.F.R. § 802.401 that the Committee intends to conclude all action under section 721 with respect to that transaction, each party that has submitted additional information subsequent to the original declaration must file a certification as described in 31 C.F.R. § 802.202 via the Case Management System portal. 

The requirements for the certifications, including the contents and the individual(s) who may sign the certification, are set forth at 31 C.F.R. § 802.202. Sample certifications can be found below:

Real Estate Notice Submission

Parties to a transaction that choose to file a notice of the transaction with CFIUS must do so in accordance with the procedures under 31 C.F.R. § 802.501.  Please refer to the CFIUS Overview page for a summary of the notice submission process.


CFIUS does not issue advisory opinions as to whether a transaction might raise national security concerns or be considered a covered real estate transaction subject to review.  Parties to a transaction are encouraged to consult with CFIUS in advance of filing a notice and/or to file with CFIUS a draft notice or other appropriate documents describing the transaction.  Such steps both aid the Committee’s understanding of the transaction and provide an opportunity for the Committee to request that additional information is included in the formal notice.  Any such pre-notice consultation should take place, or any draft notice should be provided, at least five (5) business days before the filing of a voluntary notice.  All information and documentary material provided to the Committee as part of pre-notice consultations is accorded confidential treatment pursuant to § 802.802.


Starting on June 1, 2020, all real estate notices, including draft notices, must be filed via the Case Management System online portal.  See the Case Management System page for more information.

Required Contents of a Notice

The regulations at 31 C.F.R. § 802.502 specify the required contents of a voluntary notice.  

Encryption and File Security

CFIUS supports efforts to help protect the security of sensitive data filed with CFIUS.  File encryption is a useful tool to ensure that sensitive data remains secure.  Note that information submitted to CFIUS through the Case Management System is automatically encrypted.

Individual File Encryption: CFIUS can receive encrypted Microsoft Office and Adobe Acrobat (.pdf) files and may be able to receive other file format encryption as well; please contact CFIUS for more information.  Submit the encrypted file(s) through the Case Management System.


The CFIUS Overview page provides a detailed description of the notice process. 


Parties to a transaction that file a voluntary notice with CFIUS are required in every case to provide two types of certifications: a certification at the time of filing that covers the contents of the voluntary notice (§ 802.502(h)) and a certification at the conclusion of a review or investigation covering all additional information filed subsequent to the original notice (§ 802.502(l)).

The final certification will be requested several days before the end of the review or investigation and should be submitted through the Case Management System portal at least one or two days before the anticipated closing date of the review or investigation.  A review or investigation cannot close without the certification, and failure to provide a final certification by Day 45 of the review or Day 45 of the investigation is grounds for rejection of the notice.

The requirements for the certifications, including the contents and the individual(s) who may sign the certification, are set forth at § 802.202. Sample certifications can be found below:
