[9] The law's purpose in allowing attorney's fees and costs to a wife who has not sufficient monies to meet such expenses is to assure to women with domestic difficulties that they will have their day in court, on appeal as well as at the trial. [10] Four conditions must concur to warrant an allowance of attorney's fees in such a case as this: (1) The wife must be in need of such assistance--if she has ample funds of her own to retain counsel no requirement that her husband pay counsel fees is justified; (2) The husband must have the ability to pay; (3) The proposed appeal must be taken in good faith; (4) There must be a reasonable ground for the appeal; this does not mean that the appellant must be assured of success, but that reasonable men should believe that the contentions to be urged merit attention and resolution by an appellate court.
