In some of the previous Harvest Moon games your spouse would help you out on the farm in various ways, but this isn't the case in all the games in the series. I'm hoping that A New Beginning falls into the former group, but FOGU doesn't mention anything. The A New Beginning "Married Life" and "Child" sections are still works in progress though, so there could be benefits not currently covered on the site.
Are there any benefits to getting married, or will my spouse just hang around my farm instead of around town?
