Scope and Content

Series consists of estate files containing the original documentation filed with the court in proceedings leading to a grant of probate or administration.

Typically, an estate file includes the original will in cases of probate, administration bonds in cases of administration, petitions for probate or administration and supporting affidavits, and the order for probate or administration.

While some inventories of estates exist for the early period, the occurrence of these in the files becomes more frequent after 1892 when the Succession Duty Act required detailed inventories and lists of heirs to be included in the files of taxable estates. When the value of taxable estates was lowered by an amendment to the act in 1907, the presence of these inventories and lists becomes even more common.

If the will or the grant of probate or administration was contested, the estate file should also include the caveat filed against the estate, relevant citations and affidavits, and the final judgment issued by the court.

Series also contains custody applications made to the Thunder Bay District Surrogate Court under the authority of the Infants Act (1911). Under the Infants Act, a parent or third party could apply for custody of, or access to, a child by making application to the Surrogate Court of the county or district in which the child was residing. In making an order the court was required to consider the rights of both parents and the best interests of the child.

Files are arranged numerically by application (non-contentious business) number.
