Definition
A contractual or statutory phrase obligating a grantor to transfer real property to a grantee by means of a deed that is both legally valid in form and substantively effective to pass clear, marketable title. The phrase operates as a shorthand standard of quality in agreements to sell or transfer land, imposing on the conveying party a dual obligation: (1) the instrument of transfer must be formally sufficient—properly executed, acknowledged, and delivered—and (2) the title conveyed must be good—free from undisclosed encumbrances, adverse claims, or defects that would expose the grantee to legal challenge.
The phrase most commonly appears in contracts for the sale of real estate, testamentary directions to executors or trustees, and enabling statutes authorizing fiduciaries to dispose of land. When a contract requires a party to "convey by good and sufficient deed," courts have generally interpreted this as requiring a warranty deed, or at minimum a deed whose covenants are adequate to protect the grantee against prior claims.

Common Confusion
"Good and sufficient" is sometimes treated as redundant, as though both words mean the same thing. They do not. "Good" speaks to the quality of the title being conveyed—whether the grantor actually holds what is being transferred and whether it is unencumbered. "Sufficient" speaks to the adequacy of the instrument itself—whether the deed is properly drafted, executed, and acknowledged to accomplish the legal transfer. A deed can be formally sufficient but convey bad title, and conversely a grantor can hold good title but execute a defective instrument. Courts enforcing contracts containing this phrase have at times treated one element in isolation; researchers should be alert to which dimension is actually at issue in any given case.
The phrase is also occasionally confused with a simple covenant of warranty. A warranty deed covenants against future disturbance of possession by parties claiming through the grantor; a "good and sufficient" conveyance standard encompasses the broader question of whether the deed is adequate to pass title at all, and whether title was good at the moment of conveyance.

Why It Matters in Research
This phrase is primarily a creature of contract drafting and statutory language from the nineteenth and early twentieth centuries, and its meaning was frequently litigated in state courts during that period. Researchers will encounter it most often in three contexts: (1) equity suits to compel specific performance of land sale contracts, where the question was whether the tender of a particular deed satisfied the contractual standard; (2) probate and trust proceedings, where instruments directing a fiduciary to "convey by good and sufficient deed" raised questions about what type of deed satisfied the direction; and (3) early state recording and conveyancing statutes that used the phrase to describe the standard of instrument eligible for recording or capable of passing title against third parties.
The phrase's meaning shifted somewhat between jurisdictions and over time. In early Connecticut and Massachusetts decisions, courts focused on the formalities of execution and acknowledgment as the primary content of "sufficient." Later New York and Pennsylvania decisions—more commercially oriented—tended to fold marketable title requirements into the "good" component, making the combined phrase a functional equivalent of a marketable title obligation. Researchers working across jurisdictions should not assume that a Connecticut decision from 1870 and a New York decision from 1890 are using the phrase to mean the same thing.
The Rapalje & Lawrence reference traces this phrase into cases construing agreements to "convey real estate" and related covenant language. The connection to warranty deed jurisprudence is significant: 4 Paige (N.Y.) 628 treats the question of what covenants are implied or required when a party promises to convey by a deed meeting this standard, and the answer in New York courts trended toward requiring full covenants of warranty. Researchers in the Law Mind corpus should link searches on this phrase to broader research on specific performance of land contracts, marketable title doctrine, and the historical law of covenants running with land.
Because modern conveyancing practice has largely standardized deed forms by statute, this specific phrase is less common in contemporary drafting. Its primary research value today is in construing historical instruments and in understanding what obligations courts imposed on sellers and fiduciaries in the period before uniform conveyancing acts.

Historical Dictionary Support
Rapalje & Lawrence index this phrase under conveyancing covenant contexts, cross-referencing warranty deed obligations (4 Paige N.Y. 628, 638), the definition of conveying real estate (29 Conn. 356, 365), and the broader law of conveyances including questions of acknowledgment, recordability, and scope (5 Mass. 472; 23 Minn. 34; 45 Miss. 245). The entry's structure reveals that nineteenth-century practitioners understood "convey by good and sufficient" as touching several distinct legal questions that today's researchers might classify separately: title quality, instrument formality, and covenant content.
What historical dictionaries do not supply is a clean doctrinal synthesis. The case citations in Rapalje & Lawrence scatter across formality questions (is acknowledgment necessary?) and substantive title questions (what covenants are required?) without clearly separating them. This reflects the state of the doctrine at the time—courts were still working out whether "good and sufficient" was primarily a formal standard or a substantive title standard, and the answer varied by jurisdiction and by context (contract versus statute versus testamentary direction).
No single historical dictionary entry captures the phrase as a unified doctrine. Researchers should treat the Rapalje & Lawrence references as a jumping-off point into case law rather than as a settled definition.

Jurisdictional Note
New York courts tended to interpret this phrase as requiring a warranty deed with full covenants, making it a substantively demanding standard. Connecticut and Massachusetts decisions emphasized formal sufficiency—proper execution and acknowledgment—as the core requirement. Researchers should not import the New York construction into New England materials, or vice versa, without checking local authority.
