What happens when I turn 18?

From the day you turn 18, your Child Trust Fund will turn into a matured CTF account, meaning it will have the same benefits and charges as before, but it will be closed to any new investment. The matured CTF will remain the same as before until you tell us what you want to do with your investment.

We can’t accept new contributions into a matured account (even from you) so any direct debits will stop on, or before, your birthday but the annual charges on the account will remain the same as before (£25+VAT on a shares account or 0.7% of investments for a stakeholder account).  We can help start direct debits up again if you transfer into a new account though.

You’ll receive a letter from us around the date of your 18th birthday asking you to make a decision about your investment. You’ll need to download and fill out the ‘CTF maturity election form’ (which can be found on our make an election page) and send it back to us whatever decision you take with your account. Please note you can only do this once you’ve turned 18, but you don’t have to make a decision right away.

You can find the list of options available to you from your 18th birthday by using the button below.

What should I do now?

Between now and your 18th birthday, you should have a think about what you want to do with the money invested when you turn 18. Your parents or guardians could play an important role in your decision-making process so it would be beneficial to discuss your options with them.

Whilst we can’t accept an instruction about the future of your investment until you are 18, there are a couple of things that you can do now.

Firstly, let us know how you’d prefer us to communicate with you.  Up until now, we’ve mainly dealt with your parent or guardian but once you are 18, we’ll only communicate directly with you (unless you tell us otherwise). Complete and return the form below, which is designed for you to fill in so that we have your preferred contact details – it also allows you to provide details of anyone you’d like to help you with the account once you turn 18.

It’s important we have your correct contact details in order to update you with any actions you may need to take regardless of which option you decide to choose.  We need to know where you live, especially if this is different to your parent’s address, as we’ll need you to provide proof of your address (there’s more information about that below).

If you’ve already turned 18 and know what you’d like to do with the money invested, visit our election page to find out what you need to do.

Another thing that you can do now is send us documents to prove your identity and where you live. This is an important step to make sure that we know who you are and that only you have access to the funds that have built up for you. You can’t take money out of, or add money into, your matured account until you’ve done this.   

You may also want to send us proof of your bank details. This allows us to make future withdrawals directly into your bank account and/or set up future regular investments from that account.

You can send the documents into us when you are ready to make your decision about what to do with your account. However, it’s a good idea to send these documents now to help avoid delays in acting on your instruction.  

To verify your identity, we can accept

  • Valid passport
  • Valid photocard driving licence (full or provisional)
  • Recent evidence of entitlement to a state or local authority-funded educational or other grant
  • Most recent HM Revenue and Customs Tax Coding Notification, Assessment or Statement (dated within the last year). If you are working and paying tax, the HMRC will send you a copy of your tax coding notification on request.
  • A government-issued document that incorporates your full name and photograph and either your residential address or your date of birth.

We then need something that has been sent in the post to your residential address.   

  • A bank or debit card statement which has been issued within the last three months (but not ones printed off the internet). If you don’t normally get these sent in the post, if you contact your bank, they can usually send you a one-off statement.
  • Utility bill issued within the past three months (but not ones printed off the internet)
  • Valid photocard driving licence (full or provisional)*
  • Recent evidence of entitlement to a state or local authority-funded educational or other grant*
  • Most recent HM Revenue and Customs Tax Coding Notification, Assessment or Statement (dated within the last year)*
  • A government-issued document that incorporates your full name and photograph and either your residential address or your date of birth*

* We need two documents so you can’t use the same document to confirm both your identity and your address.

To verify your bank details, we need something from your bank which has your sort code, account number and account name printed on it e.g.

  • A bank statement which has been issued within the last three months (but not ones printed off the internet). If you don’t normally get these sent in the post, if you contact your bank, they can usually send you a one-off statement.  We can accept the same statement as both proof of your bank details and proof of your address.
  • A voided cheque (in other words, one that you have scored through and written VOID across it so that nobody could use it)
  • A pre-printed pay-in slip

We don’t recommend that you send us originals of personal documents in the post.  However, you can send us certified copies instead. 

Certified means that the person who copies your original document needs to confirm that they have seen the original document(s).    

To certify a document, the certifier takes a copy of the document.

On each page they need to include

  • The statement (it can be stamped or handwritten) “I hereby certify this is a true copy of the original”
  • The date (the certification must be within the last 6 months)
  • Their signature
  • If the copy of your photographic identification (e.g. passport) is not clear, they should also state that it is a good likeness of you.

They also need to provide their full name and designation (e.g. job title), badge/reference/registration number if applicable and clearly note their full address details and telephone number. This is because we need to be able to separately confirm their identity e.g. through a professional register.  

We can only accept documents certified by people with certain professions.   They cannot be someone related to you.  They could be a family friend and they need to be currently practicing (e.g. not retired)

The certifiers we can accept are:

  • A judge or a magistrate
  • A senior civil servant
  • A serving police or customs officer
  • A commissioner for oaths
  • An officer of an embassy, consulate or high commission of the country or territory of issue of documentary evidence of identity
  • A lawyer, notary public or legal executive who is a member of a recognised professional body
  • An actuary who is a member of a recognised professional body
  • An accountant who is a member of a recognised professional body
  • A member of the Institute of Chartered Secretaries and Administrators
  • A director or officer (working within the Legal or Compliance office) of a regulated financial firm
  • The UK Post Office certification service, with details of the individual certifier

The certifier should sign and date each document, and state on each document

  • Their name, address and telephone number
  • The capacity in which they are certifying the documents
  • Their firm if applicable
  • Their badge/reference/registration number if possible

Unlike when you apply for a passport, the person certifying your documents doesn’t need to know you personally.

If you don’t know someone that you can ask either personally or professionally, the Post Office offer a certification service for a small fee.

We don’t recommend that you send us originals of documents such as a passport or drivers’ licence in the post.  However, you may feel more comfortable sending us original documents such as tax notices or bank statements.

The account will remain open and any funds already received will remain invested. You can transfer to another account within BMO.  However, you cannot add further payments to or withdraw funds out of the account (including transferring to another provider).  Online access to your account may also be restricted.

If we don’t have proof of your bank details, then if you make a withdrawal, we send the proceeds to you by cheque to your registered address.

Please send them to us in the post to:

BMO Asset Management Ltd
PO Box 11114
Chelmsford
Essex
CM99 2DG

You can send them in at the same time as the “Update my Contact Details” form above but if you are sending them separately, then please make sure that you provide your account number.
