When a representation ends, your obligation to the client does not immediately end with it. ABA Model Rule 1.16(d) requires attorneys to take steps at termination to protect client interests, which includes providing reasonable notice, delivering papers and property to which the client is entitled, and refunding unearned fees. Part of that protection is maintaining the client file long enough to be useful if something comes up later.
How long is long enough? That depends on your state. Retention requirements vary significantly across jurisdictions, and the consequences of early destruction range from bar discipline to malpractice exposure if the destroyed file would have been relevant to a later claim.

What ABA Model Rule 1.16 Actually Requires
The ABA Model Rules do not specify a retention period. Rule 1.16(d) requires that upon termination, an attorney take steps to protect the client's interests. The ABA's formal opinions have interpreted this to mean that files must be retained for a "reasonable period" after the representation ends, with guidance leaning toward five years as a general minimum in the absence of a specific state rule.
More importantly, the ABA's position is that the file belongs to the client, not the firm. Absent specific direction from the client, the attorney must either return the file to the client or retain it long enough that the client can meaningfully access it if needed. Destroying a file without client notice and consent before the client has had an opportunity to retrieve it is a Rule 1.16 violation regardless of how old the file is.
Before destroying any client file, the standard best practice is to send the former client written notice of the intended destruction date and offer to provide the file or specified portions of it before that date.
State-by-State Retention Minimums (Key Jurisdictions)
Where states have specific rules or formal ethics opinions, those govern over the ABA's general guidance. The following are key states where specific guidance exists:
| State | Minimum Retention Period | Source |
|---|---|---|
| California | 5 years after last active date (general); 7 years for criminal defense | State Bar of CA Ethics Opinion 2001-157 |
| New York | 7 years after matter closed | NY Rules of Professional Conduct; NY State Bar Op. 780 |
| Texas | Reasonable period (no specific rule); 5+ years recommended by State Bar | Texas State Bar Ethics Hotline guidance |
| Florida | 6 years (trust accounting records); no specific rule for other file contents | Florida Rules of Professional Conduct 5-1.2 |
| Illinois | 7 years recommended; permanent for certain estate and real property matters | ISBA Ethics Opinion 94-13 |
| Pennsylvania | No specific rule; 5-7 years recommended | PA Bar Association guidance |
| Ohio | No specific rule; 7 years recommended | Ohio State Bar guidance |
| Georgia | 6 years after matter closed (statute of limitations alignment) | State Bar of Georgia Ethics Opinion 87-5 |
If your state is not listed or you practice across multiple states, consult your state bar's ethics resources or contact the ethics hotline. Most state bars have formal ethics opinions on file retention that are publicly available.
What Belongs in a Client File vs What You Can Discard
Not everything associated with a matter needs to be retained for the full period. The distinction that matters is between the client's file and the attorney's work product.
The client's property, which must be returned to the client or retained until they claim it, includes: documents and instruments the client entrusted to you, original wills, deeds, and executed agreements, and anything the client paid you to obtain on their behalf.
The attorney's property, which you may retain, includes: attorney notes, drafts, internal memoranda, research files, and other work product created during the representation that was not delivered to the client.
The practical issue is that most practice management systems do not make this distinction automatically. Everything goes into the matter folder. When a matter closes, you need a documented process for identifying what is the client's property (to be returned or held for the retention period), what is your retained work product (held per your retention policy), and what is administrative documentation (billing records, correspondence, held per your trust accounting and file retention policy).
Trust Account Records: The Separate Requirement
Trust account records are subject to a separate and typically longer retention requirement than the general client file. Most states require trust account records to be retained for five to seven years. The ABA's ethics opinions suggest that trust accounting records should be retained for at least seven years given the statute of limitations for conversion claims.
Trust account records that must be retained include: client ledger cards or electronic records showing each client's balance, bank statements, deposit slips, cancelled checks or bank images, wire transfer records, reconciliation worksheets, and any documents supporting individual transactions.
Note that trust accounting records and the matter file may have different retention periods. An attorney may be permitted to destroy a five-year-old client file while still being required to retain the trust account records associated with that matter for another two years.
Electronic File Retention and Destruction
Electronic files present two challenges that paper files do not: they are easier to retain indefinitely (storage is cheap), and they require affirmative action to destroy securely (deletion does not equal destruction).
On retention: the fact that it is easy to keep digital files forever does not mean you should. Files containing client confidential information are a security liability. A breach affecting a 10-year-old closed matter may create less harm than a breach affecting active matters, but it still creates disclosure obligations and potential bar discipline. Retaining files indefinitely is not a compliance strategy.
On destruction: deleting a file from your practice management system does not necessarily destroy the underlying data. Depending on your system and backup architecture, the data may persist in backups, archived storage, or system logs. A compliant electronic file destruction process confirms that the data has been purged from active storage, backup storage, and any other locations where it persists.
Building a File Retention Policy for Your Firm
A written file retention policy does four things: it tells staff how long files are kept, it triggers the destruction process at the right time, it documents compliance with bar requirements, and it protects you if a former client or bar investigator asks why a file was destroyed.
Minimum elements of a file retention policy:
- Retention periods by matter type (general litigation, criminal defense, estate/trust, real property, corporate)
- Responsibility for tracking matter close dates and triggering the retention clock
- Client notice procedure before destruction (form letter, notice period, method of delivery)
- Documentation of destruction (log of what was destroyed, by whom, on what date)
- Destruction method for paper (shredding) and electronic files (certified deletion or media destruction)
Most law firms do not have a written file retention policy. Files accumulate indefinitely because no one has created a process to close them out. That approach works until a bar inquiry, a former client's request, or a storage crisis forces the question. The firms with written policies spend less time managing file questions and more time on active matters.
