Some of the decedent's property may never enter probate because it passes to another person contractually, such as the death proceeds of an insurance policy insuring the decedent or bank or retirement account that names a beneficiary or is owned as "payable on death", and property (sometimes a bank or brokerage account) legally held as "jointly owned with right of survivorship".

In general, the probate process involves collecting the decedent's assets, liquidating liabilities, paying necessary taxes, and distributing property to heirs. Probate procedures are governed by state law and have been the subject of debate and reform since the 1960s. The Uniform Probate Code (UPC) was first proposed in 1969 by the National Conference of Commissioners on Uniform State Laws and the House of Delegates of the American Bar Association. The prime focus of the UPC is to simplify the probate process. The UPC, which has been amended numerous times, has been adopted in its entirety by 16 states: Alaska, Arizona, Colorado, Florida, Hawaii, Idaho, Maine, Michigan, Minnesota, Montana, Nebraska, New Mexico, North Dakota, South Carolina, South Dakota, and Utah. The other 36 states have adopted some part of the UPC but still retain distinct procedures.
You can also write a letter of instruction to leave step-by-step instructions as well as spell out your personal wishes for things like your funeral or what to do with your digital assets like social media accounts. If you're married, each spouse should create a separate will, with plans for the surviving spouse. Finally, make sure that all the concerned individuals have copies of these documents.
A party may challenge any aspect of the probate administration, such as a direct challenge to the validity of the will, known as a will contest, a challenge to the status of the person serving as personal representative, a challenge as to the identity of the heirs, and a challenge to whether the personal representative is properly administering the estate. Issues of paternity can be disputed among the potential heirs in intestate estates, especially with the advent of inexpensive DNA profiling techniques. In some situations, however, even biological heirs can be denied their inheritance rights, while non-biological heirs can be granted inheritance rights.[41]
^{Intentional destruction: pursuant to Section 14 of the Wills Act of Malaysia a will can be burnt, torn or otherwise intentionally destroyed by the testator or a third party in the presence of the testator and under their direction, with the intention to revoke the will. Accidental or malicious destruction by a third party does not render the revocation effective.[citation needed]}
_{Estate planning is an ongoing process and should be started as soon as an individual has any measurable asset base. As life progresses and goals shift, the estate plan should shift in line with new goals. Lack of adequate estate planning can cause undue financial burdens to loved ones (estate taxes can run as high as 40%), so at the very least a will should be set up—even if the taxable estate is not large.}
To challenge the caveat, the intended executor sends a completed “warning” form to the probate registry. This document will be sent to the person who entered the caveat, and for the caveat to remain, they will have to enter an appearance at the probate registry.[33] This is not a physical appearance; it is a further document to send to the probate registry within eight days of receiving the warning.[33]
Assets that could make up an individual’s estate include houses, cars, stocks, artwork, life insurance, pensions, and debt. Individuals have various reasons for planning an estate, such as preserving family wealth, providing for a surviving spouse and children, funding children's or grandchildren’s education, or leaving their legacy behind to a charitable cause.

an order of court appointing a person to administer the estate of a deceased person. Where a person dies leaving a will that makes an effective appointment of executors, the executors' title to deal with the deceased's estate is completed by the issue of a grant of probate. This is in fact and in law (like a grant of LETTERS OF ADMINISTRATION) an order of the High Court. Probate maybe either in common form (where the probity of the will is not in dispute), issued by one of the Probate Registries, or where the will is disputed in solemn form. Contentious business is dealt with in the Chancery Division; non-contentious business is assigned to the Family Division.
Before exploring the types of probate, we want to express our option that if you have been named as the executor of an estate, probating a will is not something that you should try to do alone. As the executor, you have the fiduciary responsibility to make sure all estate matters are handled properly, and experienced legal counsel is essential to avoid needless mistakes and delays in the probate process.
Only a person having some interest that will be affected by the probate can contest it. Such persons include next of kin who will receive property if the will is set aside and intestacy results, purchasers of property from the heir or heirs, administrators or personal representatives under prior wills, and the state, if there is a possibility of Escheat, which means that the government will receive the property if no living heirs can be found. Creditors, however, generally are not entitled to contest the will of a debtor.
A testator can enter into a contract with her or his heirs in which they agree not to contest a will. If the contract is supported by consideration—something of value—and the agreement is otherwise valid, the heirs will be prevented from contesting the will. The beneficiaries under a will and the heirs can enter into a valid contract not to contest a will. States vary as to the remedies a party to an agreement not to contest a will has upon breach. These include an Injunction against the prosecution of the contest, an action at law for damages, or a defense to the contest.
Because life insurance proceeds generally are not taxed for U.S. Federal income tax purposes, a life insurance trust could be used to pay estate taxes. However, if the decedent holds any incidents of ownership like the ability to remove or change a beneficiary, the proceeds will be treated as part of his estate and will generally be subject to the U.S. Federal estate tax. For this reason, the trust vehicle is used to own the life insurance policy. The trust must be irrevocable to avoid taxation of the life insurance proceeds.
