A married woman, who, by the custom of London, trades on her own account, independently of her husband; so called, because, with respect to her trading, she is the same as a feme sole. Jacob, Dict.; 1 Cro. 63; 3 Keb. 902; 2 Bish. M. W. § 528. The custom was recognized as common law in South Caro- lina, but did not extend beyond trading in merchandise; 1 Hill, S. C. 429; 2 Bay 164; under it a woman could not be a feme sole carrier; 1 McMullan 50. By statute in several states a similar custom is recog- nized; thus in Pennsylvania, by act of Feb. 22, 1718, the wives of mariners who had gone to sea were recognized as feme sole traders when engaged in any work for their livelihood, and by act of May 4, 1855, the benefits of this act are extended to all those wives whose husbands, from drunk- enness, profligacy, or other cause, neglect or refuse to provide for them, or desert them; 2 P. & L. Dig. 2895. By the latter act she may make application to the court of common pleas and obtain a decree and certificate that she is authorized to do busi- ness under said act; id. It is not neces- sary that there should be a decree in order that a wife may have the benefit of the act; it is remedial, and to be construed be- nignly; 59 Pa. 18; 131 id. 241; mere non- support does not entitle her to the privi- leges of the act; there must be profligacy, drunkenness, or wilful absence or neglect; 110 Pa. 486; but if, deserted by her husband, she engages in business, she cannot be held liable as a feme sole trader unless she has been decreed such: 34 Leg. Int. 5. She may convey her real estate by deed in which her husband does not join; 95 Pa. 472; and the title passes free from any claim of the husband as tenant by the curt- esy; 104 Pa. 298; in which the act was de- clared constitutional. The husband is liable for necessaries, notwithstanding the wife has been declared a feme sole trader; 9 Phila. 236; and actual residence with her husband does not take away her privileges under the act; 101 Pa. 371; and so in South Carolina; 2 Bay 163; 2 Bish. M. W. § 528. As her powers are in some respects greater than those of a married woman under the act of June 8, 1893, there is no reason for regarding the early Pennsylvania acts as superseded by the later act; 2 P. & L. Dig. 2895, note. In North Carolina the doctrine that a feme covert may be a sole trader was con- sidered with deliberation, and it was held that it did not obtain in that state; 1 Jones, Eq. 1. In an appeal from the Dis- trict of Columbia it was said by the su- preme court that "the law seems to be settled that when a wife is left by her hus- band, without maintenance and support, has traded as a feme sole, and has obtained credit as such, she ought to be liable for her debts," whether the husband was ban- ished for crime or abandoned her; but by Maryland law a deed of real estate acquired by her while a feme sole trader, abandoned by her husband, was held void; 1 Pet. 105. In California under a sole trader act, ex- cluding from the benefits of the act a mar- ried woman carrying on business in her own name, but managed by her husband, it was held that she could not escape liabil- ity as sole trader on the ground that she permitted such management; 43 Cal. 105. See 24 Miss. 416. A married woman by statute authorized to carry on trade and perform labor or ser- vices on her sole and separate account, is personally liable on a note given for prop- erty purchased for business purposes; in such a case the court said: "The power of a married woman to make contracts relat- ing to her separate business is incident to the power to conduct it. The power to engage in business would be a barren and useless one disconnected with the right to conduct it in the way and by the means usually employed." 53 N. Y. 422; id. 93; 106 id. 74. ...
