Divorce in Montana

The Law Follows the Gold:

How Montana Territory Learned to End a Marriage

A Camp Without a Court

In 1863 the miners at Bannack and Alder Gulch lived in Idaho Territory, and the territorial government sat in Lewiston. A University of Montana account of the period, drawing on the standard history by Michael Malone, Richard Roeder, and William Lang, describes Lewiston as hundreds of miles away over snowbound passes, and says the miners believed it could never govern them properly (Graetz and Graetz). A Bozeman historian puts the journey at a hard week's travel (Kramer). A husband or wife in the diggings who wanted a court to end a marriage would have found the nearest machinery for doing so a long way off.

The settlers petitioned for a territory of their own. Congress created Montana Territory by the Organic Act of May 26, 1864 (United States, Congress). Governor Sidney Edgerton, who had arrived at Bannack in September 1863 as a newly appointed Idaho chief justice, made that camp the capital (Graetz and Graetz). The first Legislative Assembly met there from December 12, 1864, through February 9, 1865, and passed nearly 100 bills ("Montana Territorial Legislative Assembly (1st: 1864)"). On February 7, 1865, the members voted to move the capital to Virginia City (Graetz and Graetz).

What Congress Left to the Courts

The Organic Act supplied the territory with a governor, a secretary, three judges appointed by the president, and an elected legislature ("Montana Territorial Legislative Assembly (1st: 1864)"). Until the legislature provided otherwise, the governor could define the judicial districts and assign the judges to them (United States, Congress).

A companion act, amending the first, bears directly on divorce. It authorized the county probate courts to hear civil cases involving up to five hundred dollars, and criminal cases that did not require a grand jury. It withheld from them any jurisdiction in chancery or divorce causes, and it allowed appeals from probate courts to the district court (United States, Congress). The probate judge in a mining county could therefore settle a debt but not dissolve a marriage. That work belonged to the higher courts, presided over by judges the president had appointed.

The Statute of 1871

The earliest territorial divorce statute documented in the sources consulted dates to 1871. According to the Montana Historical Society's legal timeline, Chapter XXII of the laws passed by the Seventh Legislative Assembly set out the grounds. They were adultery, a preexisting marriage, natural impotence, habitual drunkenness, a year's unexplained absence from the territory, conviction of a felony, and extreme cruelty. If the couple kept living together after one of these events, the ground no longer applied ("Montana Women's Legal History Timeline"). The Society's archives hold records of that session, including the report of a Code Commission, though the finding aid does not say what the commission addressed ("Montana Territorial Legislative Assembly (7th: 1871)").

A second Society publication summarizes the work of historian Paula Petrik and describes the grounds in similar terms, adding that women most often charged their husbands with desertion, adultery, cruelty, or drunkenness (Montana Historical Society, "A Man"). The two lists differ at the edges. The timeline does not name desertion, and the summary names bigamy where the timeline names a preexisting marriage. The sources do not reconcile this, and later amendment may explain it.

The law did not stand still. The timeline records that in 1879 the legislature expanded the divorce chapter to allow alimony to a divorced wife and to waive legal fees for a wife too poor to pay them ("Montana Women's Legal History Timeline"). Petrik's central argument, as the Society summarizes it, is that women who sued for divorce pushed the territory's law toward easier divorces on terms more favorable to women (Montana Historical Society, "A Man"). Her full article, "If She Be Content: The Development of Montana Divorce Law, 1865-1907," appeared in the Western Historical Quarterly in 1987 (Petrik).

A Frontier Habit

Petrik found that conditions in mining towns such as Helena and Butte made divorce common (Montana Historical Society, "A Man"). In 1868 a Helena resident, Elizabeth Chester Fisk, observed that "a man in the mountains cannot keep his wife." The Society's summary says the remark rested on fact: in Lewis and Clark County in 1867, divorces outnumbered marriages.

The summary offers several reasons. Men far outnumbered women, which let a woman improve her economic position by leaving one husband for another. One Silver Bow County woman said as much in her own divorce proceeding, according to the summary. Montana's liberal law was consistent with other western states and territories, the Society adds (Montana Historical Society, "A Man"). The Society's account does not suggest that Montanans were unusually troubled by the rate, which in some places approached modern levels.

Who Judged Cruelty

The people who decided these cases were men. The Society's summary states that judges, and juries in contested cases, were all male, as were most lawyers. The legal timeline supports this for juries: an 1874 act limited jury service to white men of lawful age (Montana Historical Society, "A Man"; "Montana Women's Legal History Timeline").

The ground that required the most judgment was cruelty. The 1871 statute used the phrase "extreme cruelty," but the legislature did not define it until 1907, thirty-six years later ("Montana Women's Legal History Timeline"). In the interval the courts defined it case by case. Judges often applied what the Society's summary calls a "three beating rule," a practice that appeared nowhere in the statute. A woman might have to prove several episodes of violence, not one.

The Montana Supreme Court addressed the question in Albert v. Albert (1885), reported at 5 Mont. 577. Kate Albert petitioned the Second District Court of Deer Lodge County for a divorce from her husband, Charles. He said he had struck her once, and that she had provoked him by accusing him publicly of adultery. The trial judge told the jury that provocation could excuse harsher treatment, and the jury denied the divorce. On appeal the Supreme Court reversed. It held that a single act of physical violence by a husband could establish extreme cruelty, and that a wife's words could never excuse a violent response (Scherer).

The decision did not change practice everywhere. The Society's summary reports that judges in Butte, a working-class city, kept applying the conservative multiple-incident standard after 1885. Meanwhile, middle-class and upper-class women in Helena were arguing that cruelty need not be physical at all. They sued on grounds of mental cruelty, and one woman cited the humiliation of her husband's public escort of known prostitutes (Montana Historical Society, "A Man").

Then the court retreated. Scherer reports that in Ryan v. Ryan (1906) the Supreme Court held that Albert had been superseded by a statute requiring grievous bodily injury. The legislature responded by amending the law to include the threat of such injury (Scherer). The 1907 act defined extreme cruelty to include the infliction or threat of grievous bodily injury, false charges against a wife's chastity, and grievous mental suffering lasting a year before the suit ("Montana Women's Legal History Timeline"). The Society's summary agrees that the legislature added mental cruelty in 1907 and attached the one-year requirement. It observes that the requirement, in effect, gave an abusive spouse a year of grace (Montana Historical Society, "A Man"). The observation is the Society's, and the statute's text, as quoted in the timeline, supports its description of the requirement.

Where the Records Are

For researchers, the key fact is that divorce records before 1943 are county records. According to the Library of Congress, divorce records before 1943 are held by the clerk of the district court in the county where the decree was issued, and state-level records begin in 1943 (Library of Congress). The FamilySearch catalog gives one concrete example. It lists microfilm of Deer Lodge County divorce files from 1890 to 1950, copied from the originals in the district court clerk's office in Anaconda. The catalog notes that the files were pulled from all civil cases and so have gaps in their numbering, and that some divorces were filmed out of sequence ("General Index"). A researcher looking for an individual divorce, or for the whole run of cases that Petrik studied, has to work county by county.

Legislative records are a separate matter. The Montana Historical Society Research Center in Helena holds the manuscript journals, bills, and committee reports of the territorial assemblies, including the first session and the seventh ("Montana Territorial Legislative Assembly (1st: 1864)"; "Montana Territorial Legislative Assembly (7th: 1871)").

A Note on the Evidence

Several points deserve candor. No source consulted identifies the first divorce granted in Montana, and this article makes no claim about it. The earliest divorce statute documented here is the 1871 act, and the sources consulted do not say whether the legislature that met at Bannack in 1864 and 1865 passed a divorce law of its own.

Some details rest on a single source. Petrik's article is available only by subscription, so its findings are taken from the Montana Historical Society's summary. That covers the 1867 comparison of divorces and marriages in Lewis and Clark County, the Fisk remark, the "three beating rule," and the Butte and Helena contrast. The 1879 provisions on alimony and fees appear only in the legal timeline. The Albert v. Albert facts come from Scherer, with the reversal and the Butte aftermath corroborated by the Society's summary, and the case itself was not consulted directly.
