Old documents can take up space, but some are worth keeping for years. Certificates, tax records, legal papers, property documents and financial records may be needed long after they were first issued.
You may need them for identity checks, jobs, mortgages, pensions, probate, family matters, tax questions or official applications. Keeping the right documents can save time and help avoid stress later.
Identity and family certificates
Some personal certificates should usually be kept permanently.
Important documents include:
- birth certificate
- marriage certificate
- civil partnership certificate
- divorce document
- change of name deed
- adoption certificate
- death certificate of close family member, where relevant
- naturalisation or citizenship certificate
These documents can be difficult or time-consuming to replace, especially when they are needed urgently.
Education certificates
Education documents may be needed years after school, college or university.
Keep:
- GCSE certificates
- A-level certificates
- BTEC certificates
- degree certificate
- academic transcripts
- professional qualifications
- training certificates
Employers, universities and professional bodies may ask for proof of qualifications long after you completed them.
Employment records
Employment records can help with references, pensions, tax and background checks.
Useful documents include:
- employment contracts
- offer letters
- payslips
- P45s
- P60s
- reference letters
- redundancy letters
- settlement agreements
- professional registration documents
You do not always need every payslip forever, but key annual and legal records are worth keeping.
Tax records
Tax documents can be important if HMRC asks questions or if you need to prove income.
Keep records such as:
- P60s
- P45s
- self assessment tax returns
- tax calculations
- tax year overviews
- HMRC letters
- national insurance records
- VAT records, if applicable
- accountant letters
Self-employed people should also keep invoices, receipts and business expense records for the required period.
Property documents
Property documents can be needed when buying, selling, remortgaging or dealing with inheritance.
Keep:
- title records
- mortgage documents
- lease documents
- tenancy agreements
- deposit protection certificates
- completion statements
- planning permission
- building regulation certificates
- guarantees and warranties
- service charge records
Missing property documents can delay a future sale.
Financial documents
Some financial records are worth keeping for future applications or disputes.
This may include:
- bank statements
- savings records
- loan agreements
- credit agreements
- pension statements
- investment records
- insurance policies
- mortgage statements
- proof of large transfers
These can help with mortgages, probate, tax, banking checks or source of funds questions.
Legal documents
Legal documents should be kept safely and clearly labelled.
Important records include:
- will
- lasting power of attorney
- court orders
- probate documents
- solicitor letters
- contracts
- divorce financial order
- child arrangement order
- statutory declarations
- settlement agreements
Tell a trusted person where key documents are stored, especially wills and powers of attorney.
Medical and care records
Some medical documents are worth keeping, especially if they relate to long-term conditions, children, insurance or care.
Useful records include:
- vaccination records
- allergy information
- prescription lists
- hospital letters
- specialist reports
- care plans
- disability documents
- medical insurance records
These can help when changing doctors, travelling, applying for insurance or arranging care.
Digital copies
Digital copies make documents easier to find, but they should not always replace originals.
Good practice includes:
- scanning important documents
- using clear file names
- storing files securely
- backing up documents
- keeping originals safe
- avoiding only storing documents on one device
For legal, identity and certificate documents, originals may still be required.
Common mistakes to avoid
People often throw away documents that later become useful.
Common mistakes include:
- throwing away old certificates
- losing name change documents
- not keeping P60s
- discarding property guarantees
- failing to save pension statements
- relying only on screenshots
- not backing up digital records
- keeping documents without labels
- storing originals somewhere unsafe
- forgetting where wills or legal papers are kept
Final thoughts
Old documents worth keeping include certificates, tax records, legal papers, property documents, education records, pension statements and important financial paperwork.
You do not need to keep every letter forever, but key documents should be stored safely and reviewed regularly. A simple filing system can make future applications, legal matters and family admin much easier.
