Derivative claims

The Family Law Act and Derivative Claims

Ontario’s Family Law Act (the FLA) creates a cause of action (i.e. grounds to file a lawsuit) for the family member of anyone who has been injured or killed as a result of the fault or negligence of another person. This includes the negligence of a health care professional.

Who is Considered a “Family Member”?

Under the FLA, a “family member” is an immediate family member only, and includes a spouse, parents, grandparents, brothers, sisters, children, and grandchildren.

What Can Family Members Claim For?

Family members may file a claim for:

  • Expenses that were reasonably incurred “for the benefit of the person injured or killed”;
  • Reasonably incurred funeral expenses;
  • A reasonable allowance for travel expenses incurred while visiting the injured person during their treatment or recovery;
  • A reasonable allowance for nursing, housekeeping, or other services provided for the injured person, or for loss of income resulting from these activities
  • Compensation for loss of guidance, care, and companionship that the family member may have reasonably expected to receive from the person had their injury or death not occurred.

What Does This Mean in a Medical Malpractice Case?

In the context of a medical malpractice case, this means that a family member can make a “derivative claim” that is secondary to the main medical malpractice lawsuit.  In many cases, these derivative claims can be significant, sometimes in the hundreds of thousands of dollars.

At Sommers Roth & Elmaleh, a large portion of the derivative claims that we bring on behalf of clients have to do with extraordinary expenses and time that parents or family members have spent caring for a disabled child (i.e. a claim for “services provided” by the parents to that child) or for loss of income as a result of providing those services.

Services Provided

Parents often seek to recover damages for services or care provided to their injured child in the wake of a medical error. Questions that commonly arise in the context of such a claim include:

  • Were the services or care provided reasonably required;
  • What is the value of those services or care?

Services or care provided to a child injured by medical error or negligence vary depending upon the severity of the injuries. However, care and services can include things such as grooming, changing diapers, feeding through feeding tubes, hygiene, monitoring for seizures, therapy or skills development, accompanying to the hospital or appointments, etc. Where a parent can establish that such services or care were reasonably required, they can claim damages for that care. Caselaw has recognized that such expenses can be claimed even where the injured child is in hospital, rehabilitation, or care facility.

The larger question in such cases often becomes what is the monetary value of such services provided by parents? There are generally two approaches used in such cases. One involves calculating a general global total, which is the approach most often proposed by defense counsel.  The other involves calculating cost for services based on an hourly rate.  In some cases, the hourly rate is calculated using the rate charged by personal care workers or agencies.

Loss of Income

Family members can claim their own income loss resulting from the death or injury suffered by their parent, spouse, child, sibling or grandchild.

In many cases, income loss due to an inability to work because of bereavement or assisting an injured family member is sufficient grounds to make a claim. However, there may be limits to what is reasonable.

Medical malpractice claims and derivative claims stemming from medical error and negligence should be handled by lawyers with extensive experience in this area and the knowledge necessary to skillfully and effectively guide clients through this process.

    Dear Mr Hilik Y. And Jeremy Syrtash. I would like to express my deepest gratitude to you and Sommers Roth and Elmaleh Professional Corporation staff for all you have done with respect to my wife case. My wife was a victim of Medical Malpractice after giving birth to our daughter. She become legally disabled both physically and mentally. The entire family devastated emotionally as my wife struggle to cope with the new reality. The case of Medical Malpractice is quite often a complex case to prove. However, due to your strong commitment, knowledge and dedication combined with strong professionalism the case was successfully won after a long arduous fight. The victory would not have been possible without your dedication and thorough research in the implementation of the standards of the Sommers Roth and Elmaleh Professional Corporation. Justice prevailed at last which in turn allowed my vulnerable wife to feel more optimistic about her future and that of our family. The positive outcome of this case has changed our lives forever. It would not have been possible without the excellent representation of Sommers Roth and Elmaleh Professional Corporation and its legal counsel. My wife and I will be deeply grateful for the successful outcome of this case for many years to come. Solomon Regassa

From the first day I sat in Hilik's office, not once did I feel apprehensive. My concerns and worries were put at ease due to the kindness and compassion of Hilik, Jeremy and Fanny and their relentless persistence to secure my daughter's future. This has been a long but successful endeavor during some difficult times and through it all, the Team has been resilient, informative and were always available.

    I was in a serious horse accident where the horse was injured and should never have been ridden. The owner of the horse was aware that the horse had chronic arthritis issues and the veterinarians at Guelph had told him the horse could decompensate at any time and could cause serious injury whether being led or ridden and could never be jumped again. The horse had been shown at the grand prix level and the owner had payed quite a bit of money for him. After consulting with several lawyers and having one that did represent me at the discoveries who later quit, Jeremy Syrtash took on the case and followed through with guelph university. That is how we found out that the vets had recommended the above. Without Jeremy's efforts and follow through the case would never have continued on. Because of these efforts the case was successful. Thank you so much Jeremy. You are a dedicated, thorough, excellent lawyer and it's been a pleasure to have you as my lawyer!!

    We want to start by saying how much we highly recommend Sommers, Roth and Elmaleh for anyone who is dealing with a situation involving medical malpractice. Hilik and the entire firm have allowed us the opportunity to give our little girl the life she deserves. There is no taking back what happened, but they truly turned such a tragedy into a victory. They fought long and hard, and put forth so much time and effort into making the individuals accountable and responsible for the mistakes that were made. They always showed true compassion for our family, guided us with ease, and supported us through every step. This was such a life changing experience with the firm, and honestly we will always be forever grateful and thankful.
