An LLP tells Companies House about a new member on LL AP01 (LL AP02 for a corporate member), a departure on LL TM01, changed personal details or a change of designated status on LL CH01 (LL CH02 for a corporate member), and a new registered office on LL AD01. Member appointments, departures and changes of details must be notified within 14 days, and most can be filed online.

Which law now governs LLP member filings?

For most of the life of the LLP regime, section 9 of the Limited Liability Partnerships Act 2000 set the rules for notifying membership changes. That section was omitted with effect from 18 November 2025 by the Limited Liability Partnerships (Application and Modification of Company Law) Regulations 2025 (SI 2025/1033). The duties now sit in sections 167G to 167L of the Companies Act 2006, applied to LLPs in modified form by regulation 17A of the Limited Liability Partnerships (Application of Companies Act 2006) Regulations 2009. In practice this brings LLP member filings into line with the director filing rules that companies follow.

The same date marked the start of mandatory identity verification at Companies House. Companies House updated LL AP01, LL CH01 and LL TM01 on 18 November 2025 to reflect the new registers and identity checks, so older paper versions kept in a practice file should not be reused. For background on how LLPs are formed and run, see our guide to limited liability partnerships.

Which form do I use for each change?

Event Form Deadline
Individual becomes a member LL AP01 14 days from the day the person becomes a member
Company or other body becomes a member LL AP02 14 days
Any member leaves LL TM01 14 days from the day the person ceases to be a member
Individual member’s name, service address, residential address or country of residence changes LL CH01 14 days from the change
Corporate member’s details change LL CH02 14 days from the change
Existing member becomes or stops being a designated member LL CH01 (or LL CH02) Treat as part of the same 14 day routine
LLP moves to “all members are designated”, or back to specified designated members LL DE01 Takes effect once delivered
Registered office moves LL AD01 Effective when registered

The 14 day periods come from sections 167G(7) and 167H(3) as applied to LLPs, and each runs from the day of the event itself, not from when the paperwork is signed.

What has to go on an LL AP01 for a new member?

Under the modified section 167G(4), the notice of a new member must include the required information about that person, a statement that the person has consented to act, a statement that the individual’s identity is verified, and a statement that the person is not disqualified under the directors disqualification legislation (or details of any court permission or sanctions licence that allows them to act). For an individual, the required information under section 167J is name, date of birth, nationality, any relevant former names, a service address (which may be “The LLP’s registered office”), usual residential address and the part of the UK or country where they usually live.

LL AP01 asks for the new member’s Companies House personal code and confirmation that they have verified their identity, and it asks whether the person is being appointed as a designated member. If you tick that box, the appointment and the designation are notified together. Our page on Companies House identity verification explains how members get a personal code. Corporate members of LLPs are among the roles for which Companies House will introduce identity verification later.

How are designated members changed?

Section 8 of the 2000 Act lets members become or stop being designated members by agreement with the other members. It also contains a safety net: if there would otherwise be no designated members, or only one, every member is a designated member (section 8(2)). GOV.UK guidance says an LLP must have at least two designated members at all times, and that designated members carry the extra statutory duties, such as signing and filing accounts and the confirmation statement.

There are two different filings, and they are often confused:

  • Changing an existing member’s status. Use section 7 of LL CH01 (“Change of status of member”) for an individual, or LL CH02 for a corporate member. The form records that the person consents to act as a designated member, or as an ordinary member.
  • Changing the LLP’s whole approach. Use LL DE01, filed under section 8(4), to give notice either that every member from time to time is a designated member, or that only specified members are designated. LL DE01 says it cannot be used to change the designation of existing members, and that separate forms should be sent for any existing member whose status changes as a result.

Where every member of the LLP is a designated member, the modified section 167G(3) means the LLP does not have to notify a person’s designation separately from their membership.

How does an LLP change its registered office?

File LL AD01, which can be done online. Under section 87 as applied by regulation 16 of the 2009 Regulations, the change takes effect when Companies House registers the notice, but for 14 days after registration a person may still validly serve documents at the old address. The new address must be an “appropriate address”, meaning that, in the ordinary course of events, documents delivered there by hand or post would be expected to come to the attention of someone acting for the LLP and delivery can be acknowledged (section 2(5) of the 2000 Act), and a home address used as the registered office will be public. Companies House says a paper LL AD01 is needed if the LLP has been moved to the Companies House default address, is in liquidation, or is applying to be restored. Our page on registered office address rules covers the appropriate address test in more depth.

Who signs, and can the forms be filed online?

The paper LL AP01, LL CH01 and LL DE01 must be authenticated by a designated member (or a judicial factor). GOV.UK guidance also lists telling Companies House about changes to members and the registered address among the responsibilities of designated members. Companies House encourages online filing because paper takes longer, and an LLP signed up to the PROOF (protected online filing) scheme must not use paper versions of these member forms.

What happens if a filing is late?

Missing the 14 day deadline without reasonable excuse is an offence under the modified section 167L, committed by the LLP and every member in default. There is a second, more practical consequence for incoming members. Under the modified section 167N, where a person joins an LLP after incorporation and notice is not given within the 14 days, that person may not act as a member until the notice is given. A person who acts in breach commits an offence, although their acts as a member remain valid. Separately, an individual must not act as a member unless their identity is verified (section 167M as applied).

How does this work in practice?

Illustration only. Three architects run a design practice as an LLP with two designated members, A and B. On 2 March, C joins as a member and the members agree that C will also be a designated member. On 20 March, B retires.

  • C must have verified their identity and given their personal code. The LLP files LL AP01 for C, ticking the designated member box, by 15 March (14 days beginning on 2 March).
  • B’s departure is filed on LL TM01 by 2 April. Because B ceases to be a member, B automatically ceases to be a designated member (section 8(6)).
  • After B leaves, A and C are the two designated members, so the minimum is still met. Had C not been designated, the section 8(2) safety net would have applied.

If the practice also took a bank loan secured over its assets, that charge would be registered separately on LL MR01, as explained in our guide to registering a charge.

What mistakes do LLPs commonly make?

  • Using the company forms (AP01, TM01, AD01) instead of the LL versions.
  • Treating designation as automatic. Unless every member is designated, a new member is only designated if that is agreed and notified.
  • Filing LL DE01 to change one person’s designation, when LL CH01 or LL CH02 is the correct form.
  • Letting a new member act before their appointment is filed late, or before their identity is verified.
  • Updating the service address but not confirming that the residential address is unchanged; the modified section 167H(4) requires that statement.
  • Treating the Companies House filing as the end of the job. A new member’s terms can also affect how they are taxed, so check the salaried member rules when someone joins on a fixed share.
