How do you start a class action lawsuit?

There are a few things consumers should know about how to file a class action lawsuit. In order to start a class action of any kind, a person must have a cause of action that is shared by a significant number of others. The class action lawsuit is based on the old principle of strength in numbers and allows a large number of plaintiffs to bring legal action against a powerful defendant when individual lawsuits are not practical.

That said, the entire process begins with a single plaintiff or a small group (two to three) individuals who have suffered the same harm by the defendant.

Who Is Eligible to File a Class Action Lawsuit?

Virtually anyone with a valid cause of action can start a class action lawsuit, provided they meet certain qualifications. Primarily, this means the one who files must demonstrate a number of things, which are defined under Federal Rule of Civil Procedure Number 23:

  • Adequacy — Is/are the lead plaintiff(s) able to represent the class in a fair and adequate manner?
  • Ascertainability — In other words, can all potential plaintiffs be identified?
  • Numerosity — Are there enough plaintiffs to justify granting class status?
  • Commonality — Do all plaintiffs have the same cause of action?
  • Typicality — Is/are the class representative(s) typical of the other class members?

In addition to the above, the lead plaintiff(s) must prove the cause of action is serious enough to warrant the court’s involvement. Furthermore, the class representative(s) must be able to answer affirmatively to at least one of three questions raised under Rule Number 23(b):

  • would filing separate, individual lawsuits create a risk of inconsistent verdicts?
  • would a court order (injunctive or declarative relief without the involvement of a jury) be appropriate in light of the cause of action as it relates to all class members?
  • are there common questions of law that would make a class action preferable to individual lawsuits?

Any injured party who can meet the above requirements is eligible to start a class action lawsuit.

How Many Plaintiffs Are Required to File a Class Action Lawsuit?

How to start a class action lawsuitThere is no hard and fast number. A class action may be started by one individual, or a dozen. All that is necessary is that all potential plaintiffs have the same cause of action, i.e., the same specific complaint against the defendant. The one who initially files the class action typically becomes what is known as the “lead plaintiff,” and will have many additional responsibilities — but that person also gets an extra share of any settlement, provided the class action is successful.

 What Happens After a Class Action Has Been Filed?

Once the papers have been filed, the case goes before a judge, who will review the complaint and determine whether there is a sufficient number of plaintiffs with the same cause of action as well as other factors. If the judge determines that the case has merit and there are enough qualified petitioners, s/he will allow the case to move forward.

Are There Financial Incentives for a Lead Plaintiff?

As noted earlier, the lead plaintiff is entitled to extra compensation for working closely with the attorney(s), attending all court proceedings and generally representing the other class members before the judge and jury.

How Much Does It Cost to File a Class Action Lawsuit?

Typically, there are no up-front costs to start a class action lawsuit. Once they have determined that the case is strong enough, lawyers who specialize in this type of litigation represent the class on a contingency bases, meaning they front all initial costs of filing and moving the case forward.

If the case ends in a settlement or a verdict in favor of the plaintiffs, the lawyer(s) take a percentage of the judgment (generally one-third). It is a risk for them as well as the lead plaintiff(s), because if the defense prevails, they receive nothing.

What If Some Class Members’ Complaints are Different?

If all plaintiffs’ cases are not identical, this is not necessarily a deal breaker. Such a situation is covered under Federal Rule of Civil Procedure Number 23(c)(4), which allows for the establishment of “subclasses.” Forming subclasses is appropriate under the following circumstances:

  • Some class members are seeking different relief than others — for example, some plaintiffs want the defendant to pay for health monitoring, while others are seeking monetary compensation
  • Some groups among the class members have slightly different, but related facts
  • There are groups from different jurisdictions with varying rules of evidence

While a class action can be sustained with a few subclasses, too many may result in a decision by the court to deny class certification  on grounds that “common questions [of law] do not predominate.”

How Long Does It Take to Resolve a Class Action?

There is no good answer to this question. While some class action lawsuits can be resolved in a few months, many of them go on for two years or more. It all depends on the strength of the claim, preponderance of evidence and the complexity of the case.

Ideally, lawyers on both sides will be able to negotiate a satisfactory settlement before the case goes to trial; this is considered the best outcome in most cases. The only drawback is that typically, when a defendant agrees to a settlement, they are not required to admit any liability or wrongdoing.

What Is the Difference Between a Class Action and Multidistrict Litigation?

While both involve multiple plaintiffs, the parties in a class action are legally considered to be a single plaintiff.  In multidistrict litigation (MDL),  plaintiffs share judicial resources and pre-trial procedures (such as discovery, expert testimony, etc.), but retain their individual lawsuits.

What Does a Person Need Before Approaching an Attorney?

Most lawyers and firms specializing in class action litigation offer free initial consultations, either in person, online or over the telephone. During this session, the lawyer will want to make certain that the claim is a valid  one, as cases deemed to be frivolous tend to be dismissed quickly.

One  should be prepared to provide documentation of the complaint (such as photos, receipts, etc.) before they start a class action lawsuit. The lawyer will then research similar past cases and attempt to learn whether or not any laws have been broken, and how many other people have been affected by the same kinds of issues.

Class action lawsuits can be filed in myriad areas, including civil rights, defective products, medical problems, false claims and more.

    I would like to start a class action suite against Door Dash for the excessive additional fees incurred for delivery and the increased pricing of the menu items. The fees also vary and change with no explanation of what they are for. Paying for the dash pass is supposed to reduce delivery charges and fees but you still end up paying a increased price which is deceptive advertising

    Walmart Store 281 in Heber Springs Arkansas had a small equipment fire on 12/14/23. The post can be seen on the local fire department’s fb page (Heber Springs Fire Department). They remained open even though the store smelled of smoke and items throughout the store were covered in soot. It is said that management had the employees wiping items off including food/produce. They remained open all day on friday 12/15/23 and sold these items and continued to stock items from the back rooms where the damage occurred. Employees were having to work in those back rooms with the smoke and soot. It wasn’t until 12/16 that the store closed and had a restoration company come in. They had employees back to work cleaning the store. This is for the employees that had to work in those conditions as well as people like myself that were shopping in the store that day that bought these items that were smoke and soot damaged/covered without knowing. Today, after selling these food items to people for an entire day, they are throwing food out.

    I’m interested in filing a class action lawsuit against the makers of Lime-A-Way..the product container does NOT state that it is only for toilet bowls.. I used it to remove lime buildup on my kitchen faucet and it ran down into my stainless steel sink causing significant damage.. the company refuses to take any responsibility even though Ive sent photos of the product bottle and the damage

    I would like to start a class action lawsuit against Rakuten. They neglect to give you cash back on items that you spend $$$$ on but prefers to give you cash back on smaller priced items. Particularly when shopping at Macys through their app. Once you report that you are missing the cash back they advise that it takes up to 45 days to hear back from the store. Once the 45 days are up and nothing has been confirmed by the store they give you a credit meanwhile I assume they have already received the commission from the large purchase made but refused to give you the money you suppose to received.

    I want to file a lawsuit against Catholic Cemeteries. We bought plots 30 years ago but have decided to be cremated. CC wants to charge us 15-25% for “breaking the contract” and not being buried there! We are only allowed to sell the plots back to CC and we will only get what we paid for them 30 years ago MINUS the penalty amount of 15-25%

    I recently bought Gorilla Glue and Loctite glue. After several months, both solidified in their tubes. The Loctite glue was never opened. Calls to both manufacturers informed me that there is a 6-18 month life span for the product before it will solidify.
    This is not stated anywhere on the products or their package.
    Imagine how many customers are purposefully deceived by this held back information.
    PLEASE CONSIDER THIS FOR A NEW CLASS ACTION LAWSUIT. Thank you.

  7. Carmen Cade says:

    I just received a letter giving me an apology for the incident, but my hospital says that my medical information was leaked through a third party, though they don’t see that anything has been used. Can they simply just send us a “my bad” in the mail and give us information about fraud protection? I need help deciphering whether or not this is cause for a class action lawsuit. I’m glad I found this article.

  8. Mary Jackson says:

    I would like to start a class action suit against DR Horton. The houses over priced and are constructed of cheap material and are put together in a hurried manner- therefore rushing through / not completing projects.
    The warranty department refuses to fix some items and or assigns tickets to companies that do not call or show, holding the homeowner hostage.
    There are also other problems not mentioned.

  9. Jerry C says:

    Having migraine headaches I purchase Excedrin Migraine. Excedrin Migraine contains the EXACT (including quantity) medicine as Excedrin Extra Strength, except Excedrin Migraine is roughly 30-40% more expensive than Excedrin Extra Strength. This is an example of the Pink Tax. I have seen previous cases similar to this and would like to know how to go forward.

    I would like to start a class action lawsuit against DoorDash. I myself with many others have lost 100 hundred of dollars due to door dash not refunding us back our money when our food was either stolen or not delivered at all. Upon looking under the BBB I have found many others as well on social media has experienced the same scenario. We come in numbers.
