Definition

A Roman civil law term referring to the security or surety given by a party to a legal proceeding — typically a defendant — guaranteeing payment of whatever judgment might ultimately be rendered against that party. The satisdatio operated as a formal pledge of satisfaction: the party provided assurance, whether through money, sureties, or another recognized form, that any adjudicated obligation would be fulfilled.

The concept extended beyond purely adversarial proceedings. In Roman law, certain persons in non-litigious legal contexts — notably tutors (guardians) and administrators of trust-like arrangements — were required to furnish satisdatio as security for the faithful discharge of their duties, much as English law would later require trustees and guardians to post bond.

Why It Matters in Research

Satisdatio is exclusively a Roman and civil law term. Researchers encounter it almost entirely in three contexts: (1) English treatises and commentaries on the civil law tradition, particularly those engaging with Justinian's Institutes; (2) historical materials on equity procedure, where Roman procedural concepts informed early chancery practice; and (3) discussions of guardian and trustee bond requirements, where comparativists drew explicit parallels between Roman satisdatio and English suretyship rules.

The Blackstone reference (3 Bl. Comm. 291) is the key English-language anchor. Researchers tracing the concept through common law commentary should start there to understand how English jurists received and domesticated the Roman idea. The term does not survive as operative vocabulary in American or English positive law — it functions as a historical and comparative reference point rather than a working term in modern pleading or procedure.

Corpus researchers should be alert to the fact that Rapalje & Lawrence's entry is incomplete as printed (the entry breaks off mid-sentence), which is a transcription artifact of the original source. The substantive content from Black's and Burrill's supplies what Rapalje omits.

Historical Dictionary Support

All four source dictionaries agree on the core definition: satisdatio is security given by a party to proceedings to guarantee payment of what may be adjudged. Black's (both editions) and Burrill's track almost identically, each citing Inst. 4, 11 and 3 Bl. Comm. 291 — the standard twin authorities for this term in the Anglo-American tradition.

Burrill adds the most context of the four sources, specifying that the security pledged in the Roman judicatum solvi formula was the operative mechanism — the party bound themselves to satisfy (solvere) whatever was judicially determined (judicatum). This precision is useful: satisdatio was not merely a promise but a formal pledge with legal consequence if dishonored.

Rapalje & Lawrence, though truncated in the available text, makes the most important comparative contribution by drawing the explicit parallel to English trustee and guardian bond requirements. The observation that a tutor not appointed by will or after inquiry was typically required to furnish security parallels the English rule requiring court-appointed guardians to post bond — a connection that helps researchers working in the history of fiduciary law trace doctrinal lineage.

None of the historical dictionaries engage with the procedural mechanics of how satisdatio was furnished or enforced under Roman procedure — for that level of detail, researchers must go beyond these dictionaries to Roman law treatises.

SATISDATIOmain

Rapalje & Lawrence • 1883

-In Roman law, was the security (consisting in money or in some other form) given by certain persons in certain legal proceedings, whether actions or not; usually, a trustee or tutor, unless appointed by will or ex inquisitione (i. e. after inquiry), was required (just as in English law) give ive security for his faithful administration of the trust. And in actions, a person suing or being sued per procuratorem (i. e. by proxy) was required to give the to satisdatio called "de rato," otherwise "ratam rem dominum habiturum" (i. e. that his principal use of in cases where satisfaction is implied from the ambiguous acts or language of testators or settlors. Thus, if a parent, bequeaths a legacy to a child by way of portion, and afterwards (e. g. upon the marriage of the child) gives him a sum by way of portion, the latter sum generally operates as a satisfaction of the former, either completely or pro tanto; i. e. the child cannot claim the legacy on the death of the parent. So, if a testator gives a would ratify or abide by the result whatever it legacy to his creditor, it operates as a was). And a defendant had usually to give also satisfaction of the debt, provided that the the satisdatio called "judicatum solvi," i. e. that the judgment (if against him) would be carried legacy is equal to or greater than the debt, out by him-which carrying out involved in the and that no contrary intention appears. case of lands the restitution of the possession and also of the interim rents and profits (prædes litis et vindiciarum). There was also a species of satisdatio called "pro suâ tantum personá," i. e. for the person of the defendant only, and this in English law corresponds to bail by defendant to appear in a personal action.-Brown.
