Does a New York lawyer have to keep a firm's thousands of old, closed client files indefinitely, or can the lawyer dispose of files no one has asked for?
NYSBA Ethics Opinion 1192: Retention and Disposition of a Lawyer's Closed Files
Short answer: The opinion concludes that, apart from important exceptions, nothing in the Rules requires a lawyer to keep unsought closed client files indefinitely; the lawyer must indefinitely retain original documents of intrinsic value (wills, deeds, negotiable instruments) and documents the client or a third party may still need, and must keep certain bookkeeping records for seven years.

Plain-English summary
A lawyer who acquired a partnership interest in a financially troubled firm faced the prospect of dissolution and the burden of thousands of stale closed client files with no connection to any ongoing client, where disposal would be costly. The lawyer asked what obligations a lawyer has in dealing with closed client files.
The opinion reaffirms N.Y. State 460 (1977): the Rules do not impose the unreasonable burden of keeping all files and records indefinitely, and what is required is determined mostly by common sense and general principles. The committee treats "client files" as primarily a matter of property law (citing Sage Realty v. Proskauer Rose), which is outside its jurisdiction; it opines only on the Rules. Under Rule 1.15(a) a lawyer holding another's property incident to practice is a fiduciary, and under Rule 1.15(c)(4) must deliver property to a client or third person on request. Assuming no one has requested return, the lawyer as fiduciary must still determine ownership before disposing of file contents. That duty runs to every firm client and is not limited to the lawyer who worked the file or diminished by joining the firm later; it survives dissolution and retirement (citing Opinion 623 (1991) and others).
The committee identifies categories that must be retained. Drawing on N.Y. City 2010-1 and the committee's own N.Y. State 1182 (2020), original documents of intrinsic value or that directly affect property rights (wills, deeds, negotiable instruments) must be kept indefinitely. So must documents the lawyer knows or should know the client or a third party may still need, such as materials potentially useful to a defense within an unexpired limitations period, or third-party property gathered in discovery or due diligence. Apart from those categories, the committee concludes that neither the Rules nor its precedents require keeping client-owned or third-party files for any fixed period unless some statute, regulation, rule, or court order says so; a commentator's suggested seven-year default is not an ethical obligation absent such a law.
Separately, materials belonging to the law firm itself (purely internal memoranda, a lawyer's notes) may generally be disposed of as the firm sees fit, unless a legal duty such as compulsory process requires preservation. But Rule 1.15(d) requires keeping specified bookkeeping records (banking and special-account records, retainer and compensation agreements, statements of disbursements, client bills, payment records, OCA filings, checkbooks and bank statements) for seven years, a duty that under Rule 1.15(h) extends to former partners and successor firms on dissolution, merger, or sale. Rule 1.10(e)-(f) also requires a firm to keep a record of its engagements to support conflict checking under Rule 1.9, with substantial failure to do so itself a violation.
In practice
Under this opinion, a New York lawyer or firm facing a pile of unsought, stale closed files is not required by the Rules to keep all of them indefinitely, but must first sort out ownership and preserve specific categories. The opinion holds that original documents of intrinsic value (wills, deeds, negotiable instruments) and documents the lawyer knows or should know the client or a third party may need must be retained indefinitely, and that the Rule 1.15(d) bookkeeping records must be kept for seven years (a duty that survives dissolution and passes to successor firms under Rule 1.15(h)). The opinion holds that this duty runs to every firm client regardless of which partner handled the matter or when a partner joined, and continues during and after dissolution.
Common questions
Q: Must a lawyer keep every closed client file forever?
A: No. Per the opinion, apart from the listed exceptions, nothing in the Rules requires keeping unsought closed files for any fixed period unless a statute, regulation, rule, or court order requires it.
Q: Which documents must be kept indefinitely?
A: Per the opinion, original documents of intrinsic value or that directly affect property rights (wills, deeds, negotiable instruments), and documents the lawyer knows or should know the client or a third party may still need.
Q: How long must bookkeeping and trust-account records be kept?
A: Per the opinion, Rule 1.15(d) requires keeping the specified records (banking records, retainer and compensation agreements, disbursement statements, client bills, payment records, OCA filings, checkbooks and bank statements) for seven years; the duty extends to former partners and successor firms under Rule 1.15(h).
Q: Does a partner who joined later, or a dissolving firm, escape these duties?
A: No. Per the opinion, the duty to maintain or arrange disposition of closed files runs to every firm client regardless of when the partner joined, and continues during and after dissolution.
Background and rules framework
The opinion interprets New York Rule 1.15 (preserving client property and required bookkeeping records), particularly 1.15(a), 1.15(c)(4), 1.15(d), and 1.15(h), together with Rule 1.10(e)-(f) (engagement records supporting conflict checks) and Rule 1.9 (former-client conflicts). These correspond to ABA Model Rules 1.15, 1.10, and 1.9. The committee treats the question of who owns file contents as a matter of property law outside its jurisdiction and confines its opinion to the Rules.
