It can be done by will, and there would probably be no problem, but....
...If it's your family home (the home in which you and your husband reside), then you can transfer the property into joint names under the Family Home Protection Act, 1976. There is no stamp duty or registration fee, although your solicitor will probably charge a fee.
The net result of this would be that you would take the house automatically by survivorship if anything happened to your husband, and there would be no necessity to go to probate for it.
It's a very straightforward transfer, so if you're planning on doing it, do negotiate fees with the solicitor.
