Renouncing probate is what you can do if you are named as executor in a deceased person’s will, and do not want to take on the role. You are not obliged to, but you need to take steps to put that into effect as soon as practical.
Note, if you are looking for executor services, you can find a lawyer or law firm to do this by contacting the law society in your state/territory for referrals: links here. Alternatively the public trustee in your state/territory, links here, also provides executor services, as do some non-government providers including banks, even if they were not consulted when the will was made.
