Definition
A bond and mortgage is a two-instrument security arrangement used in real property lending. The borrower executes both a bond — a personal promise to repay the debt — and a mortgage — a conveyance or lien on real property as collateral securing that promise. Together, they create a dual layer of protection for the lender: personal liability against the borrower and a property interest that can be enforced through foreclosure if the borrower defaults.
The bond establishes the debt and the personal obligation. It names the amount owed, the terms of repayment, and the consequences of non-payment. The mortgage ties the debt to a specific parcel of real estate. If the borrower defaults, the lender may pursue the property through foreclosure, proceed against the borrower personally on the bond, or in some circumstances both. The combination was the standard form of real property financing in American law from the colonial period through the early twentieth century.

Common Confusion
The bond and mortgage should not be confused with a deed of trust arrangement, which involves three parties — borrower, trustee, and lender — rather than two. In a deed of trust, the borrower conveys title to a trustee who holds it on behalf of the lender, and foreclosure proceeds by a trustee's sale rather than judicial action. The bond and mortgage structure is also distinct from a mortgage note, which is the modern functional equivalent of the bond but often treated as a single instrument rather than a separate formal bond. In current practice, the standalone bond has largely been replaced by the promissory note, but the underlying two-instrument logic — personal obligation plus property security — survives.

Why It Matters in Research
Researchers working in historical property records, equity court proceedings, or nineteenth-century legal documents will encounter the bond and mortgage as the dominant form of real property lending. Understanding that it was always two instruments is essential: a search that turns up only a mortgage without a corresponding bond may indicate an incomplete record, a release already executed, or a separate filing system for the bond.
In equity jurisdiction, the bond and mortgage was the province of chancery courts, not common law courts, because foreclosure required equitable relief. This means historical litigation over bond and mortgage disputes will appear in equity reports and chancery records, not in common law case reporters. Researchers unfamiliar with this jurisdictional split may miss significant bodies of relevant authority.
The personal liability dimension of the bond is a recurring research trap. Many later sources focus on the mortgage as the operative security instrument and treat the personal obligation as secondary or overlooked. In historical practice, however, lenders frequently pursued the bond independently — particularly when property values had fallen below the debt — giving rise to deficiency judgments. The law of deficiency judgments after foreclosure is, in large part, a history of courts and legislatures deciding when and whether the bond's personal liability survives a mortgage foreclosure. Anti-deficiency statutes enacted in many states during the Great Depression fundamentally altered the practical significance of the personal bond component, and that legislative history is directly traceable to the bond-and-mortgage structure.
For corpus researchers in Law Mind, the bond and mortgage connects forward to modern mortgage documentation, reverse mortgage structures, and construction financing, and backward to the entire body of colonial and early American real property law.

Historical Dictionary Support
Black's Law Dictionary defines the bond and mortgage as "a species of security, consisting of a bond conditioned for the repayment of a loan of money, and a mortgage of realty to secure the performance of the stipulations of the bond." This captures the essential structure cleanly. Rapalje & Lawrence offers no independent definition, directing readers elsewhere — a signal that by the time of that dictionary's compilation, the term was considered adequately covered by the component definitions of bond and mortgage separately.
What the historical dictionaries do not address is the practical and jurisdictional evolution of the form: the gradual displacement of the formal bond by the promissory note, the impact of anti-deficiency legislation on the personal obligation component, and the transition from judicial foreclosure (required under the bond and mortgage structure) to power-of-sale foreclosure available under deed of trust arrangements. Historical dictionaries also do not flag the recording question — in some jurisdictions and periods, the bond and the mortgage were filed separately, creating research complications for anyone reconstructing a complete transaction from archival records.

Jurisdictional Note
The bond and mortgage structure was most entrenched in states with strong equity court traditions, particularly in the Northeast and Mid-Atlantic regions. Western states, which developed their land law later, were more likely to adopt deed of trust arrangements, and many western states enacted anti-deficiency statutes earlier and more broadly. Researchers should not assume that bond and mortgage practice was uniform nationally, particularly when comparing pre-Civil War eastern sources with later western materials.
