Definition
A writ of scire facias sur mortgage is a common law judicial process used to foreclose a mortgage by compelling the mortgagor to appear in court and show cause why the mortgaged property should not be seized and sold to satisfy the debt. Issued upon the mortgagor's default — whether failure to make payments or breach of a mortgage condition — the writ directed the mortgagor to come forward and contest the creditor's right to proceed. If the mortgagor failed to appear or failed to establish a valid defense, the court would enter judgment authorizing execution against the mortgaged property.
The writ functioned as a summary enforcement mechanism. Rather than initiating a full bill in equity or a plenary action at law, the mortgagee obtained judicial authorization to foreclose through a relatively expedited proceeding grounded in the original mortgage record.
Common Confusion
Scire facias sur mortgage is frequently conflated with two related but distinct proceedings. First, it is not the same as a general writ of scire facias, which is a broad procedural device used to revive dormant judgments or enforce other matters of record — the "sur mortgage" designation is what limits and defines this writ's specific function. Second, researchers sometimes conflate this proceeding with equitable foreclosure by bill in chancery. The two operated on different tracks: scire facias sur mortgage was a common law proceeding yielding a judgment at law followed by execution, while foreclosure in equity resulted in a decree of sale or strict foreclosure through the chancery court. In jurisdictions that permitted both, the choice of proceeding carried significant practical consequences for the parties.
Why It Matters in Research
This term is almost entirely historical. Scire facias as a general procedural writ was abolished in federal practice by the Federal Rules of Civil Procedure (1938), which absorbed its functions into ordinary civil actions. State abolition followed at varying times throughout the nineteenth and twentieth centuries. A researcher encountering this term in primary sources should treat it as a strong temporal signal: the document likely predates the procedural reforms of the jurisdiction in question.
The writ is most likely to appear in early American state court records, colonial-era legal documents, and treatises on mortgage law from the eighteenth and nineteenth centuries — particularly in Pennsylvania, where scire facias sur mortgage survived as a recognized foreclosure method longer than in most other states and generated a distinct body of procedural doctrine. Researchers working in Pennsylvania legal history should be aware that this writ had a specialized local character and that Pennsylvania practice materials will be more instructive than general treatises.
A key research trap: because the proceeding was grounded in the mortgage as a record, courts interpreting scire facias sur mortgage proceedings often examined the original mortgage instrument with particular rigor. Historical case reports involving this writ will frequently turn on questions of what the mortgage itself authorized — conditions, covenants, the legal effect of the mortgage form — rather than on general debtor-creditor principles. Reading such cases without attention to the underlying instrument can produce misleading impressions about the law's content.
Researchers tracing the evolution of American mortgage foreclosure should treat scire facias sur mortgage as one branch of a three-part divergence: (1) common law foreclosure by scire facias and entry, (2) equitable foreclosure by bill in chancery, and (3) power-of-sale foreclosure under statutory authority. Understanding which track a historical jurisdiction used is essential to interpreting both procedural records and substantive mortgage law from that period.
Historical Dictionary Support
Black's Law Dictionary defines scire facias sur mortgage as a writ issued upon the mortgagor's default, requiring the mortgagor to show cause why the mortgage should not be foreclosed and the property taken and sold in execution. This definition captures the writ's essential mechanics accurately and reflects the common law structure of the proceeding.
What Black's does not convey — and what researchers should supply from other sources — is the significant jurisdictional variation in how this writ was used and how long it survived. Black's presents the writ in general terms, but in practice the writ's availability, procedure, and interaction with equitable remedies differed materially from state to state. Historical treatises on mortgage law, particularly those focused on Pennsylvania or New England practice, will provide the procedural granularity that general dictionaries omit.
Black's also does not address the abolition timeline, which is critical for contextualizing any specific document. A researcher relying solely on the dictionary definition would not know whether the writ was still available in a given jurisdiction at the relevant time.
Jurisdictional Note
Pennsylvania is the jurisdiction most associated with sustained use of scire facias sur mortgage as a distinct foreclosure method, and Pennsylvania practice developed its own body of procedural rules around the writ. Most other American jurisdictions moved earlier toward equitable foreclosure or statutory power-of-sale methods. Researchers should not assume that doctrine from one state's scire facias proceedings transfers cleanly to another's.
